  This is a brand new notebook on the market with Ryzen 5/Radeon. 
  The default kernel of Ubuntu(18.04) hangs at loading with message:

  tsc: Refined TSC clocksource calibration: 1996.250 MHz
  clocksource: tsc: mask: 0x max_cycles: (...), max_idle_ns: 
(...) 
  Soft lockup

  Using pci=noacpi kernel parameter kernel loads without any problem but
  my notebook produces more heat than on Win10. If I know right Acer
  notebooks need ACPI to the correct power management.

  The same thing happens on mainline 4.17,4.18rc1-2.
  BIOS upgrade to the latest version: 1.08 hasn't helped

  This problem has been reported upstream:
  https://bugzilla.kernel.org/show_bug.cgi?id=200087

  The latest correctly working kernel was 4.13.* but the heat problem
  was present with this too.

i only get lockups only after/before suspend sometimes, otherwise the
laptop is rock solid. however thanks Samantha for the idle=nowait boot
parameter it solved the cpu power save feature.

[Kernel-packages] [Bug 1792957] Re: Provide mode where all vCPUs on a core must be the same VM

[Kleber Sacilotto de Souza]

Hello IBM,

Could you please verify if the Bionic and Cosmic kernels currently in
-proposed resolves the issue?

Thank you.

Bug description:
  == SRU Justification ==
  This patch has been requested by IBM.  It provides a mode where all vCPUs
  on a core must be the same VM.  This is intended for use in
  security-conscious settings where users are concerned about possible
  side-channel attacks between threads which could perhaps enable one VM
  to attack another VM on the same core, or the host.

  == Fix ==
  linux-next commit:
  aa2278644ae5 ("KVM: PPC: Book3S HV: Provide mode where all vCPUs on a core 
must be the same VM")

  
  == Regression Potential ==
  Low.  Changes limited to powerpc.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.

  +++ This bug was initially created as a clone of Bug #171443 +++

  Please, add the following patch:

  http://patchwork.ozlabs.org/patch/968786/

  which adds a mode where all vCPUs on a core must be the same VM on
  POWER8 and POWER9.

  This is intended for use in security-conscious settings where users
  are concerned about possible side-channel attacks between threads
  which could perhaps enable one VM to attack another VM on the same

[samantham]

siyia: Only thing else I'd think to try would be this:
https://gist.github.com/60b73ff4e6ce901d09f9a8025826cb4a It must be run
as root and you must have `msr-tools` installed.

I wrote it just now based on https://lists.freebsd.org/pipermail
/freebsd-current/2018-June/069799.html It sets some MSR registers that
AMD specified as mitigations for some of the errata.

Let me know if that changes anything. (also I'm glad the kernel options
somehow fixed the turbo issue for you).

  After a few days of troubleshooting a problem with L2TP and IPSec a

I'm using A315-41-R8XR which doesn't have an dGPU and yet can't sleep
with noapic. Could you please specify which wi-fi adapter (lspci -k) you
are using?

[eutychios23]

your script didn't help, about the powersave it was enabled by adding
amdgpu in the modules in mkinitcpio.conf and then updating iniframs with
sudo mkinitcpio - p linux that fixed it, however after waking from
suspend cpu runs at turbo frequency again.

still freezes with c6 disabled, only anomaly I can detect is that after
resuming from sleep cpupowersave is disabled and cpu runs at turbo
frequency. only way to reverse this is to reboot and have the amdgpu
module initiated early in km.

  This is a brand new notebook on the market with Ryzen 5/Radeon. 
  The default kernel of Ubuntu(18.04) hangs at loading with message:

  tsc: Refined TSC clocksource calibration: 1996.250 MHz
  clocksource: tsc: mask: 0x max_cycles: (...), max_idle_ns:

  Soft lockup

  Using pci=noacpi kernel parameter kernel loads without any problem but
  my notebook produces more heat than on Win10. If I know right Acer
  notebooks need ACPI to the correct power management.

  The same thing happens on mainline 4.17,4.18rc1-2.
  BIOS upgrade to the latest version: 1.08 hasn't helped

  This problem has been reported upstream:
  https://bugzilla.kernel.org/show_bug.cgi?id=200087

  The latest correctly working kernel was 4.13.* but the heat problem
  was present with this too.

[Kernel-packages] [Bug 1801349] Re: zpool create -f lxd /dev/vdb fails on cosmic (18.10) -- func27

[Colin Ian King]

This is not a zfs related bug per se, it's more of a kernel related, so
I'm re-assigned the bug

** Package changed: zfs-linux (Ubuntu) => linux (Ubuntu)

Title:
  zpool create -f lxd /dev/vdb fails on cosmic (18.10) -- func27

Status in OpenStack LXD Charm:
  New
Status in linux package in Ubuntu:
  In Progress

Bug description:
  Test: tests/gate-basic-cosmic-rocky

  As part of the config, the lxd charm creates a pool device depending
  on the config.  The test config is:

  lxd_config = {
  'block-devices': '/dev/vdb',
  'ephemeral-unmount': '/mnt',
  'storage-type': 'zfs',
  'overwrite': True
  }

  The config drive is normally mounted on /mnt, and the lxd charm
  umounts it as part of the start up.  The /etc/fstab on the unit is:

  # cat /etc/fstab 
  LABEL=cloudimg-rootfs   /ext4   defaults0 0
  LABEL=UEFI  /boot/efi   vfatdefaults0 0
  /dev/vdb/mntauto
defaults,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig   
0   2
  /dev/vdcnoneswapsw,comment=cloudconfig  0   0

  
  However, even after umount-ing the /mnt off of /dev/vdb, the zpool create 
command still fails:

  # zpool create -f lxd /dev/vdb
  /dev/vdb is in use and contains a unknown filesystem.

  
  If the /etc/fstab is edited so that /dev/vdb is *never* mounted and then 
rebooted, then the zpool create command succeeds:

  # zpool list
  NAME   SIZE  ALLOC   FREE  EXPANDSZ   FRAGCAP  DEDUP  HEALTH  ALTROOT
  lxd   14.9G   106K  14.9G - 0% 0%  1.00x  ONLINE  -

scan: none requested
  config:

  NAMESTATE READ WRITE CKSUM
  lxd ONLINE   0 0 0
vdb   ONLINE   0 0 0

  errors: No known data errors

  Something odd is going on with cosmic (18.10) and the combination of
  lxd, zfs and the kernel

  lxd version: 3.6
  zfsutils-linux/cosmic,now 0.7.9-3ubuntu6

[Kernel-packages] [Bug 1800254] Re: packet socket panic in Trusty 3.13.0-157 and later

[Nivedita Singhvi]

We (Canonical Support and Sustaining Engineering) have independently tested 
fix. 
The original reporter to us has also tested and verified fix (-proposed

Title:
  packet socket panic in Trusty 3.13.0-157 and later

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Trusty:
  Fix Committed

Bug description:
  SRU Justification:

  Due to changes added as part of c108ac876c02 ("packet: hold bind lock when
  rebinding to fanout hook"), it is possible for fanout_add to add a
  packet_type handler via dev_add_pack and then kfree the memory backing the
  packet_type.  This corrupts the ptype_all list, causing the system to
  panic when network packet processing next traverses ptype_all.  The
  erroneous path is taken when a PACKET_FANOUT setsockopt is performed on a
  packet socket that is bound to an interface that is administratively down.

  This is not due to any flaw of c108ac876c02, but rather than the packet
  socket code base differs subtly in 3.13 as compared to 4.4.

  This affects only the Trusty 3.13 kernel series, starting with
  3.13.0-157.

  Fix:

  The remedy for this is to backport additional changes in the management of
  the dev_add_pack calls from 4.4.  This moves the dev_add_pack and
  dev_remove_pack calls from fanout_add and _release into __fanout_link and
  _unlink.

  Testcase:

  The issue can be reproduced reliably by (a) creating an AF_PACKET socket,
  binding it to an interface that is administratively down, and then (c)
  attempting to set the PACKET_FANOUT sockopt.  The setsockopt call will
  fail, but will corrupt ptype_all in the kernel.  Subsequent network traffic
  will induce a panic when evaulating the corrupted ptype_all entry.  A
  test program is attached.

  I recommend Canonical gets this laptop for testing since a ton of
  stuff is troublesome on this Raven Ridge laptop.  Would be a good
  specimen to get support for this platform improved.

/sys/devices/platform/AMDI0010:00/i2c-0/i2c-ELAN0732:00  and
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/AMDI0010:00/ELAN0732:00 . 
however even after loading the hid-touchscreen module, the i2c-hid module, and 
the elants-i2c module my touchscreen is not working. 
I do have some ACPI errors in my dmesg log (attached) but I am not sure they 
are related. Let me know if there is additional information I can get you.

This is the dmesg of my ubuntu 16.04 installation with the
4.14.0-041400rc7 kernel. It has the trackpad working but not its
left/right buttons.

After this kernel mainline release, the touchpad is not working at all.

[Kernel-packages] [Bug 1799401] Re: linux: 4.4.0-139.165 -proposed tracker

[Khaled El Mously]

@Paul Larson: This is expected. The commit "c714676a18f1 proc: restrict
kernel stack dumps to root" (part of the update to upstream stable
4.4.160) changed the permissions of /proc/self/stack so that it requires
either root or CAP_SYS_ADMIN

I think the test will need to be updated

[eutychios23]

installing fedora with ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
instead of noapic,produces the same soft lockup that ubuntu/arch
gets.installing it with noapic allows you to boot without any custom
parameters and acpi seems to work good.

Mine device (a315-41-R19S) can sleep on Ububtu 18.04 LTS with default kernel

Fedora 29 really do not show any errors?
On 28 there was two lines in dmesg "ioapic[4] not in ivrs table" which present 
on screenshot attachment for this bugreport.
And third line was like "switching irq routing to physical flat" - sorry, i'm 
not remember exactly... I did not find anything useful about this "physical 
flat" irq mapping mode. But seems this is similar to noapic.

  This is a brand new notebook on the market with Ryzen 5/Radeon. 
  The default kernel of Ubuntu(18.04) hangs at loading with message:

  tsc: Refined TSC clocksource calibration: 1996.250 MHz
  clocksource: tsc: mask: 0x max_cycles: (...), max_idle_ns: 
(...) 
  Soft lockup

  Using pci=noacpi kernel parameter kernel loads without any problem but
  my notebook produces more heat than on Win10. If I know right Acer
  notebooks need ACPI to the correct power management.

  The same thing happens on mainline 4.17,4.18rc1-2.

  was present with this too.

i disabled polkit auth agent from openbox autostart and now the laptop
sleeps like a baby, it was unrelated to acpi.

[Kernel-packages] [Bug 1776563]

[bakarichard91]

Hi Samantha,

thanks for your post that is a very intresting point. I thought there
was something difference between the kernels of different distros but I
didn't realize that could be caused by the pre-compile config but it's
logical.

However I'm afraid this could be just a workaround and not a correct
solution. Could you please check if you have correct ACPI functionality?
I need a dmesg output with the correct kernel and please check if the
CPU's temperature goes under 50C/122F on idle.

Thanks again.

[Kernel-packages] [Bug 1800306] Re: Computer hangs completely passed 15~25 days of usage

[Extreme Micro S.L.]

With 4.19 the computer hangs completely in a short time. It's not
related because in first place the bug only freezes video. I can enter
via ssh and get logs.

Any suggestion?

[Kernel-packages] [Bug 1776563]

[samantham]

siyia: I see you only have rcu_nocbs=0-3 but there are 8 logical cores.
Try seeing if using `rcu_nocbs=0-7 idle=nomwait` helps. Both those
together fixed my system lockups. With just rcu_nocbs for all my cores I
still got lockups (and you don't have it enabled for all cores). Ryzen

[Kernel-packages] [Bug 1776563]

[samantham]

I may be experiencing the same bug. I have a Lenovo A485 2700U. Though
the system either doesn't progress past grub's "loading initramfs" or
shows a black screen after that point.

Starting with pci=noacpi causes something to show up but it still does
not boot.

But, with a different kernel config the latest git works fine, but when
I compiled with my normal config it would not boot. Also, ubuntu's PPA
which has rc7 in it has the same issue as my normal config. I am
uploading my working and non-working config.

(here is the issue I originally reported my issue on
https://bugs.freedesktop.org/show_bug.cgi?id=108307)

  [Problem]

  In include/linux/fscache-cache.h, fscache_retrieval_complete reads, in
  part:

  atomic_sub(n_pages, &op->n_pages);
  if (atomic_read(&op->n_pages) <= 0)
  fscache_op_complete(&op->op, true);

  The code is using atomic_sub followed by an atomic_read. This causes
  two threads doing a decrement of pages to race with each other seeing
  the op->refcount <= 0 at same time, and end up calling
  fscache_op_complete in both the threads leading to the OOPS.

  [Fix]
  The fix is trivial to use atomic_sub_return instead of two calls.

  [Testcase]
  I believe the user has tested the patch successfully on their 
fscache/cachefiles setup.

  [Regression Potential]
  Limited to fscache. Small, comprehensible change.

[Kernel-packages] [Bug 1776563]

[eutychios23]

guys linpus Linux is fedora based that's why it doesn't need noapic to
boot, linpus Linux is pre-installed and supported on Acer laptops, so we
got to find what quirks is fedora using to load the bios tables
correctly.

  This is a brand new notebook on the market with Ryzen 5/Radeon. 
  The default kernel of Ubuntu(18.04) hangs at loading with message:

  Using pci=noacpi kernel parameter kernel loads without any problem but

Hi bros,

I can upload the SSDT/DSDT tables if somebody will fix them. Something
should be invented because that is not too good if linux desktops can
not be used on new notebooks.

[Kernel-packages] [Bug 1776563]

[bakarichard91]

Don't somebody want to make a comparsion (diff) from parameter to
parameter? I fixed my tables manually so I don't really have motivation
for that.

This section can be the most important for us: "Power management and
ACPI options"

Otherwise the main problem is that the kernel's ASL
(interpreter/compiler/decompiler idk.) can't interpret the ACPI tables
because of failures like this: "ACPI Error: AE_ALREADY_EXISTS, During
name lookup/catalog". If I want to decompile it with iasl the message is
the same so I need to skip some SSDT files to avoid this. After
"decompile(ing)" had been successful I need to fix a lot of bug for the
recompile(ing).

  NOTE:  I can't copy/paste from systems, as it never completes boot; I
  left it >30mins (on 755) & it just kept repeating message. I've
  manually typed it; so typo's could have been made.

  A discussion on #lubuntu-devel provided a possible cause (Thank you

   seems like it's a usb issue of some kind with 4.18
  ---

  This fits because whilst I do my testing mostly on d610 & t43 (no
  issues today), I'd tested Lubuntu 18.10 before on the dell 755 with no
  issues.  My last test was also long enough ago to be on 4.17 kernel

Bug description:
  Hello,

  I am observing all symptoms of debian bug 898060 
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=898060) on ubuntu bionic 
4.15.0-23-generic x86_64 clients
  with a Centos7 NFS server (3.10.0-693.21.1.el7.x86_64).

  After a wake from suspend the server always logs
  kernel: NFSD: client 2001:638:redacted testing state ID with incorrect client 
ID
  which is not observed with ubuntu 16.04 (kernel 4.4) clients. Sporadically 
after wake from suspend (takes days to weeks to trigger) the server logs are 
flooded with messages of the type
  kernel: RPC request reserved 84 but used 276
  and NFS on the client does not work any more. This also has not been observed 
with our 20 or so ubuntu 16.04 NFS clients in the last two years.

  Rebooting the client appears to stop the log flooding on the server
  and NFS works normally after the reboot. Remark: systemd hangs during
  shutdown, presumably waiting for the NFS mount to stop, the power
  button is the only remaining option.

  I will upgrade to the latest bionic kernel later and try to trigger
  this again.

I got a mouse from Logitech (G9x).
I changed the polling rate as per Arch wiki.

Also tried:
sudo modprobe -r usbhid && sudo modprobe usbhid mousepoll=1

cat /sys/module/usbhid/parameters/mousepoll
returned 1 so it was changing the polling rate.

However testing the actual value using the application (evhz) showed
that the mouse was stuck at 125Hz polling rate no matter what setting.

Now this would not be a to big of an issue however using the USB 3.0 port 
causes issues with Witcher 2 that causes the mouse to behave erratic
Bug (contains video): 
https://github.com/KillaW0lf04/The-Witcher-2-Issues/issues/48


When I tried to move the mouse to another USB port (2.0) then evhz started 
showing the correct polling (700-800 and peaking to 1000). The issue in the 
game with the mouse behaving erratic did also vanish. 


The polling rate issue is not the cause but a symptom of the issue so that's 
the reason I'm bringing it here. If it should be in a separate bug report 
please tell.

Any ideas?

Talk about shooting the messenger. The kernel's watchdog

the kernel's watchdog. The kernel watchdog just reports the problem. It
is also not a problem with the watchdog subsystem, which is not even

The bug in lauchpad, unless I am missing something, provides not a
single actionable traceback. I don't think it is even possible to
identify where exactly the CPU hangs unless additional information is
provided. There is no traceback in dmesg, and OopsText doesn't include
it either.

Given that, it is not possible to identify the responsible subsystem,
much less to fix the underlying problem. The only thing we can say for
sure is that it is _not_ a watchdog driver problem.

Unfortunately we do not have information to determine 'Product' and

The only information we have is that the hanging process is gnome-shell
(or at least that this was the case in at least one instance), that the
screen blinks and freezes when the problem is observed, and that the
hanging CPU served most of the graphics card interrupts. If it is
persistent, it _might_ suggest that graphics (presumably the Radeon
graphics driver and/or the graphics hardware) is involved. This would be
even more likely if the observed PCIe errors point to the graphics card
(not sure if the information provided shows the PCIe bus tree; if so I
have not found it).

Hi.

This bug [1] in the Valve github tracker seems to be caused by the hid-
steam driver, written by me, introduced in 4.18.

With this driver there is a new input device, which is disabled when the
Steam client is running. That is usually harmless, but some games go
nuts with that extra device.

I have written a patch, that instead of disabling the device, removes it
when Steam is running, and recreates it when Steam is closed.

I have submitted it to LKML a few days ago [2], but it looks like it
went through the cracks... It would be great is someone could check it.

Thanks.

  Games either:

When connecting to an Eduroam hotspot with wrong credentials, iwlwifi
prints out lots of (scary) error messages, followed by a hardware
restart.

The distro is Arch Linux, and a relevant log file is attached.

Do you have any idea if this was happening before 4.18?

Can you try our core39 release, as explained in our wiki[1] and see if
the problem still happens with that?

We had a bunch of changes in the IRQ rx handler recently, so the problem
may be solved in our internal tree already.

Here's some test result:

1. The issue does not happen (no "BUG" line or stack traces) on 4.14.72
but is reproducible on 4.18.11.

2. The issue also does not happen with the new core39 release and -41
firmware.

3. The "Unhandled alg: 0x707" line appears in all cases.

Test method:

Using 123456/123456 as username/password, and TTLS/MSCHAPv2 as the
authentication mechanism for a WPA2-EAP Eduroam hotspot. In my case, the
hotspot is provided by some Cisco device.

Fixed that in upstream backports, it'll take a while to propagate to
backport-iwlwifi, but it eventually will.

Thanks for the report!

Thanks, Johannes! I'll pull your fix into our core release soon, during
my next round of merging back from upstream.

The patch that fixes this "scheduling while atomic" issue is already in
net-next.git[1] and should go to 4.20.  When it reaches 4.20 it will be
automatically backported to the relevant stable kernels.  I could have
sent it to the 4.19-rc series, but since it's not a regression in 4.19,
I preferred to send it to -next instead.

[Kernel-packages] [Bug 1721987]

[jcs]

Obviously contacting my vendor went nowhere.

While doing more testing, I get the same result of audio only through
one speaker in Windows 10 with the default audio drivers that Windows
ships with.  The Realtek/Dolby audio drivers from the vendor (Huawei)
need to be installed in order to get sound out of both speakers in
Windows, too.

I've been playing with VFIO to be able to boot Linux and hand off the
PCI audio device to Windows 10 inside of qemu with the proper Realtek
Windows drivers installed.  This allows me to log all of the PCI IO
activity from qemu.

While doing this, I noticed that if I boot Windows 10 in qemu, then boot
Linux in qemu, audio works in Linux through both speakers with no other
changes.  This only works through qemu/VFIO, as rebooting the full
system resets the PCI device.

So something must be getting initialized or toggled on the device in
Windows that affects the device through to initialization in Linux.  One
of the pins that the device presents is configured slightly different in
Linux after booting Windows first (nid 0x19 0x41f0 -> 0x81f0),
and I've tried explicitly setting that pin configuration in Linux
without booting Windows first but it has no effect.

I have qemu logging all of the VFIO PCI reads and writes under Windows,
and I instrumented some custom code to store the RIRBLBASE and CORBLBASE
values and then print out the contents of those DMA addresses (+ current
queue offset) whenever CORBWP/RIRBWP are written to, in order to be able
to see the commands submitted to the CORB and the response from the RIRB
when running Windows.

Is there anything else similar to the CORB/RIRB that I should be logging
to try to see what else the Windows driver could be doing?

VFIO limits the emulated Windows instance to see only the PCI audio
device, so there is no ACPI configuration or other IO that it could be
doing other than PCI config read/write, PCI region read/write, and DMA
with the audio device.  But still, there must be something the

  No audio comes out of the right speaker on the laptop.  When playing a

  SRU Request [Trusty]

  == Justification ==

  It is possible to cause an oops in drm with an unimplemented ioctl call
  with the following reproducer run as root:

  #include 
  #include 
  #include 
  #include 

  int main(void)
  {
  int ptnum, fd;

  fd = open("/dev/dri/card0", O_RDWR);
  return ioctl(fd, TIOCGPTN, &ptnum);
  }

  == Fix ==

  A backport (minor wiggle) of upstream commit 1539fb9bd405
  ("drm: fix NULL pointer access by wrong ioctl").

  == Testing ==

  Run the reproducer above as root, it will trip the oops. With the fix
  this oops won't occur.

  == Regression Potential ==

  Minimal, this is an upstream fix to this exact issue and has been in
  the kernel since 3.16

  


  This is a bare-metal node running with 3.13.0-160 amd64 kernel.

  The dev test will cause kernel oops:

[Kernel-packages] [Bug 1787405] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From fre...@de.ibm.com 2018-11-07 10:16 EDT---
I installed a fresh Ubuntu 18.04.1 on a LPAR and after booting
these both packages on top:

linux-image-4.15.0-38-generic_4.15.0-38.42~lp1787405_s390x.deb
linux-modules-4.15.0-38-generic_4.15.0-38.42~lp1787405_s390x.deb

then I needed to configure zipl to something usefull as the modified
zipl.conf obviously is somewhat broken after package install:


[defaultboot]
defaultmenu=menu

[UBUNTU18.04.1]
target=/boot
image=/boot/vmlinuz.old
parameters="scsi_mod.scsi_logging_level=4605 printk.time=1 zfcp.dbfsize=100

ramdisk=/boot/initrd.img.old

[newkernel]

parameters="scsi_mod.scsi_logging_level=4605 printk.time=1 zfcp.dbfsize=100

:menu
target=/boot
1   = UBUNTU18.04.1
2   = newkernel
default = 2
prompt  = 1
timeout = 10



after boot the new kernel is active:

uname -a
Linux s83lp75 4.15.0-38-generic #42~lp1787405 SMP Mon Nov 5 21:13:01 UTC 2018 
s390x s390x s390x GNU/Linux

then I ran my brand new developed zcrypttest and all the testcases ran fine.
This is at least an indication that the zcrypt dd is not broken, multi domain 
and multi adapter works and all the 3 kinds of adapters can get addressed with 
all the different cprbs and work as expected. Even more some basic assumptions 
about request scheduling memory consumptions are tested.

What's not covered is the new functionallity coming with the apmask and
aqmask. I'll do this later as I'd like to devel some testcases for this
feature in the next days.

  [19.04 FEAT] Guest-dedicated Crypto Adapters

  == SRU Justification ==

  (Kernel SRU)

  Allow kvm to dedicate crypto adapters (and domains) as passthrough devices to 
a KVM guest such that the hypervisor cannot observe the communication of the 
guest with the device.
  (Since all kernel patches/commits are from kernel 4.19, they will 
automagically land in 'Disco'.)

Title:
  zpool create -f lxd /dev/vdb fails on cosmic (18.10) -- func27

Status in OpenStack LXD Charm:
  Incomplete
Status in zfs-linux package in Ubuntu:
  New

Bug description:
  Test: tests/gate-basic-cosmic-rocky

  As part of the config, the lxd charm creates a pool device depending
  on the config.  The test config is:

  lxd_config = {
  'block-devices': '/dev/vdb',
  'ephemeral-unmount': '/mnt',
  'storage-type': 'zfs',
  'overwrite': True
  }

  The config drive is normally mounted on /mnt, and the lxd charm
  umounts it as part of the start up.  The /etc/fstab on the unit is:

  # cat /etc/fstab 
  LABEL=cloudimg-rootfs   /ext4   defaults0 0
  LABEL=UEFI  /boot/efi   vfatdefaults0 0
  /dev/vdb/mntauto
defaults,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig   
0   2
  /dev/vdcnoneswapsw,comment=cloudconfig  0   0

  
  However, even after umount-ing the /mnt off of /dev/vdb, the zpool create 
command still fails:

  # zpool create -f lxd /dev/vdb
  /dev/vdb is in use and contains a unknown filesystem.

  
  If the /etc/fstab is edited so that /dev/vdb is *never* mounted and then 
rebooted, then the zpool create command succeeds:

  # zpool list
  NAME   SIZE  ALLOC   FREE  EXPANDSZ   FRAGCAP  DEDUP  HEALTH  ALTROOT
  lxd   14.9G   106K  14.9G - 0% 0%  1.00x  ONLINE  -

  # zpool status lxd
pool: lxd
   state: ONLINE
scan: none requested
  config:

  NAMESTATE READ WRITE CKSUM
  lxd ONLINE   0 0 0
vdb   ONLINE   0 0 0

  errors: No known data errors

  Something odd is going on with cosmic (18.10) and the combination of
  lxd, zfs and the kernel

  lxd version: 3.6
  zfsutils-linux/cosmic,now 0.7.9-3ubuntu6

No idea, but I would say if you have outdated firmware, it is definitely
worth trying updating to latest version.

  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

  I did a basic install of 16.04.1 server amd64 (accepting most of the

  encrypted. Then log on as that user and create some files. Next enable
  overlayroot by adding a /etc/overlayroot.local.conf with
  'overlayroot=tmpfs' and reboot.

  After rebooting and logging in as the user, the previously created files are 
there but the timestamps are wrong. 'stat' gives the times as:

Title:
  zpool create -f lxd /dev/vdb fails on cosmic (18.10) -- func27

Status in OpenStack LXD Charm:
  New
Status in zfs-linux package in Ubuntu:
  In Progress

Bug description:
  Test: tests/gate-basic-cosmic-rocky

  As part of the config, the lxd charm creates a pool device depending
  on the config.  The test config is:

  lxd_config = {
  'block-devices': '/dev/vdb',
  'ephemeral-unmount': '/mnt',
  'storage-type': 'zfs',
  'overwrite': True
  }

  The config drive is normally mounted on /mnt, and the lxd charm
  umounts it as part of the start up.  The /etc/fstab on the unit is:

  # cat /etc/fstab 
  LABEL=cloudimg-rootfs   /ext4   defaults0 0
  LABEL=UEFI  /boot/efi   vfatdefaults0 0
  /dev/vdb/mntauto
defaults,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig   
0   2
  /dev/vdcnoneswapsw,comment=cloudconfig  0   0

  
  However, even after umount-ing the /mnt off of /dev/vdb, the zpool create 
command still fails:

  # zpool create -f lxd /dev/vdb
  /dev/vdb is in use and contains a unknown filesystem.

  
  If the /etc/fstab is edited so that /dev/vdb is *never* mounted and then 
rebooted, then the zpool create command succeeds:

  # zpool list
  NAME   SIZE  ALLOC   FREE  EXPANDSZ   FRAGCAP  DEDUP  HEALTH  ALTROOT
  lxd   14.9G   106K  14.9G - 0% 0%  1.00x  ONLINE  -

  # zpool status lxd
pool: lxd
   state: ONLINE
scan: none requested
  config:

  NAMESTATE READ WRITE CKSUM
  lxd ONLINE   0 0 0
vdb   ONLINE   0 0 0

  errors: No known data errors

  Something odd is going on with cosmic (18.10) and the combination of
  lxd, zfs and the kernel

  lxd version: 3.6
  zfsutils-linux/cosmic,now 0.7.9-3ubuntu6

SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree or
   a minimally backported form of that patch. The following upstream
   stable patches should be included in the Ubuntu kernel:

Bug description:
  On Dell Venue 11 Pro 7140 average power consumption in idle increased
  by 1.3-1.5 times due to events coming from INT343A. According to
  powertop since Linux 4.10 INT3432:00 generate around two hundred
  events on average, in /sys/devices/pci:00/INT3432:00/i2c-6 there
  is two devices: INT343A and SMO91D0. AFAIK INT343A is rt286.

  With Linux 4.9.0-4.9.45, Linux 4.11.0-4.11.12 in idle there is around 100 
wakeups per second in sum, battery discharge rate around 3-3.5 Watts per second.
  But with Linux 4.9.46-4.9.51, Linux 4.10.0-4.10.17, Linux 4.12.0rc1-4.13.3 - 
around 300 wakeups per second on average, due to events coming from INT3432:00. 
With Linux 4.13.3 battery discharge rate around 4.5 Watts per second.
  Probably some commit was backported to Linux 4.9 between .45 and .46 releases.
  I have no idea why issue is not reproducible on any Linux 4.11 release I 
tried.

  Sometimes INT3432 events rate fall from two hundred to one hundred for
  shorts period of time (for example I observe this right now on Linux
  4.10.0 while removing/installing packages).

  Message like this sometimes appear in dmesg:
  [  731.226730] i2c_hid i2c-SMO91D0:00: i2c_hid_get_input: incomplete report 
(53/13568)

  Complete dmesg with Linux 4.13.3 is attached.

My laptop is very slow at current kernels. The frequency stucks at 800 MHz.
Latest kernel which is ok is 4.1.x (4.2 has a backlight problem).

acpi=noirq solves the problem but adds other problems...

Do you get the same result with simply "noapic"?

In both cases, powernow_k8 seems to load and print the same messages.

In the working and non-working cases, what do you see with

grep . /sys/devices/system/cpu/cpu0/cpufreq/*

What is the latest working kernel, and what is the first failing kernel?
Can you git-bisect to what commit caused this to break?

I think the regression was made in 4.2.x or 4.3.x (4.2.x kernels have a
backlight issue on my laptop, so I use 4.1.x)

what do you mean by backlight issue?
If the platform is still alive, please run git-bisect to find out which commit 
introduces the problem.

powernow-k8: Replace cpu_core_mask() with topology_core_cpumask()

The former duplicates the functionality of the latter but is
neither documented nor arch-independent.

ACPI dump

New HP EliteBook 745 G5, BIOS version 1.03.01. Ryzen PRO 2500u.

Booting any modern kernel (4.10+) hangs at boot on this system with no
kernel messages displayed unless you disable MCE support (via mce=off).

Knowing Debian's 4.9 kernel boots fine, I bisected Linus's tree, and it
appears this commit is the culprit:

x86/mce/AMD: Reset Threshold Limit after logging error

The error count field in MCA_MISC does not get reset by hardware when the
threshold has been reached. Software is expected to reset it. Currently,
the threshold limit only gets reset during init or when a user writes to
sysfs.

If the user is not monitoring threshold interrupts and resetting
the limit then the user will only see 1 interrupt when the limit is first
hit. So if, for example, the limit is set to 10 then only 1 interrupt will
be recorded after 10 errors even if 100 errors have occurred. The user may
then assume that only 10 errors have occurred.


.. although the previous few commits to this one also are all related to MCE 
support on AMD systems, so it may be a culmination of a few commits.

Bug description:
  My new Elitebook, with the latest bios 1.03.01, refuses to boot any
  kernel later than 4.10 unless mce=off is appended to the kernel
  command line.  As in, there are no kernel messages at all after grub
  (yes, quiet and splash were removed from the command line).  Perhaps
  it crashes before the efifb kicks in?

  System operates fine if mce=off is added to the kernel command line
  (and iommu=soft, but that's a separate issue, and fails with kernel
  output in that case).

  I opened upstream bug here :

  I bisected the problem down to this commit (and the few before it,

I'm using the rx580 with mesa stable and kubuntu 18.04.1 I dont have
this issue anymore after motherboard firmware update on another asrock
board but just curious would this firmware help with performance or bug
fixes on all AMD gpu?

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash

I don't know, but maybe if it's stable now you should stick with your
current configuration.

Since the 2200G is the APU chip, which has built in graphics I think I
may have experienced amdgpu and cpu-related issues (which this bug seems
to be more related to), so I've needed a combination (new UEFI and
amdgpu firmware) to get it stable.

Good questions, and beyond my ken.  "idle=nomwait" did not prevent my
system from rebooting while I was away.  (I don't know if reboots and
freezes are separate problems?)  My BIOS doesn't expose anything like
"typical current idle", and I have no way to upgrade it since the
upgrade tools require Windows.

Is there a guide out there for dummies like me to be able to collect
kernel output from these reboots?  (Does the kernel even get a chance to
do/report anything?  Would a report even be helpful to kernel hackers in
figuring out more workarounds?)  If I can contribute anything plausibly-
constructive, I'd love to.

Otherwise, I use and need this machine, so I'll probably just keep
treating the symptoms by keeping it busy.  (Which I suppose is another
software workaround. ;^)

What is the "this" that AMD have no plans to fix ?

I had a look at  which you referenced earlier.  I
found 3 MWAIT issues:

  1057 MWAIT or MWAITX Instructions May Fail to Correctly Exit From
   the Monitor Event Pending State

  1059 In Real Mode or Virtual-8086 Mode MWAIT or MWAITX Instructions May
   Fail to Correctly Exit From the Monitor Event Pending State

  1109 MWAIT Instruction May Hang a Thread

but I could not find anything else that might be related to the "freeze
when idle" problem.

FWIW, here's the full text for the Erratum 1109:

  1109 MWAIT Instruction May Hang a Thread

   Description: Under a highly specific and detailed set of internal timing
conditions, the MWAIT instruction may cause a thread to
hang in SMT (Simultaneous Multithreading) Mode.

   Potential Effect on System: The system may hang or reset.

   Suggested Workaround: System software may contain the workaround for
 this erratum.

   Fix Planned: No fix planned

so there !  I guess "idle=nomwait" is "the workaround" ?

"Typical Current Idle" appears to work for some (including me) but not
for everyone.  If one or more of these MWAIT errata is the root cause of
the "freeze when idle" problem, I wonder why AMD introduced "Typical
Current Idle" and how that relates to these MWAIT issues ??

to me. Idle freezes persists. The only thing that solved my problem was
to disable CPU C6 state through zenstates.py.

  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using 
latest BIOS available (1.52)

  We are running Ubuntu 17.04 (amd64), we've tried different kernel version, 
native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
  Tested kernel version:

  native 17.04 kernel
  4.10.15

  Issues are the same, we're getting random freeze on the machine.

  Here is kern.log entry when happening :

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

No flashing of video card or motherboard here.  I'm not using a separate
GPU - I'm using the GPU built into the Ryzen 2200G APU.  This is just
firmware loaded by the amdgpu kernel driver.

The firmware is loaded and used by the amdgpu driver as far as I
understand.  I have just replaced all of the files in
/lib/firmware/amdgpu with the latest version.

Any system that does not provides a software workaround must be affected 
according to published errata, not even a question. I've published one of their 
revision guides in my previous comments. They have no plans on fixing this and 
suggest using software workarounds. We're left on our own.

[Kernel-packages] [Bug 1690085]

[owenswerk]

I'm one of the users James mentioned early on; I don't know how to
capture kernel output when I'm greeted with a completely-locked-up or
already-rebooted machine.  If it's hardware, I don't see what the kernel
could do anyway.

I've tried all the tricks mentioned here, when applicable.  (My BIOS
doesn't expose anything like "typical current idle", etc.)

The only way I've been able to keep this system stable is to keep it
busy.  I run BOINC and donate some of this shark-style swim-or-die CPU
to medical research.  There are some nice settings for how the cores get
used, and according to htop, tasks get shuffled around to all cores, if
that matters.  I went with using at most 50% of 25% of the cores
(figures I pulled out of ...thin air).  That keeps my load average
around 2 when I'm doing nothing, but whatever - it's for a good cause.

My CPU is an AMD Ryzen 7 1800X with 8 or 16 cores depending on how one
counts, and keeping them from getting bored has, so far, let me get back
to rebooting on my terms (upgrades) rather than at random.

This comes up as a Linux problem, but it sure smells like a hardware
defect to me.  In my mind, all the self-monitoring and user-spying and
background-indexing and auto-downloading that Windows does happens to
mask this problem for most people.  (Plus who would think twice about a
randomly-hanging or -rebooting Windows box?)  Has anyone run *BSD or
FreeDOS or something else which would allow a Ryzen to get bored for
hours/days?

  Hi,

  
  We aregetting various kernel crash on a pretty new config.
  We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using 
latest BIOS available (1.52)

  We are running Ubuntu 17.04 (amd64), we've tried different kernel version, 
native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
  Tested kernel version:

  native 17.04 kernel
  4.10.15

  Issues are the same, we're getting random freeze on the machine.

  Here is kern.log entry when happening :

  Depending on the kernel version, we've got NMI watchdog errors related to CPU 
stuck (mentioning the CPU core id, which is random).
  Crash is happening randomly, but in general after some hours (3-4h).

  Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning 
and waiting for crash...
  For now, the machine is not "used", at least, it's not CPU stressed...

  
  Thanks

[Kernel-packages] [Bug 1801349] Re: zpool create -f lxd /dev/vdb fails on cosmic (18.10) -- func27

Title:
  zpool create -f lxd /dev/vdb fails on cosmic (18.10) -- func27

Status in OpenStack LXD Charm:
  New
Status in zfs-linux package in Ubuntu:
  In Progress

Bug description:
  Test: tests/gate-basic-cosmic-rocky

  As part of the config, the lxd charm creates a pool device depending
  on the config.  The test config is:

  lxd_config = {
  'block-devices': '/dev/vdb',
  'ephemeral-unmount': '/mnt',
  'storage-type': 'zfs',
  'overwrite': True
  }

  The config drive is normally mounted on /mnt, and the lxd charm
  umounts it as part of the start up.  The /etc/fstab on the unit is:

  # cat /etc/fstab 
  LABEL=cloudimg-rootfs   /ext4   defaults0 0
  LABEL=UEFI  /boot/efi   vfatdefaults0 0
  /dev/vdb/mntauto
defaults,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig   
0   2
  /dev/vdcnoneswapsw,comment=cloudconfig  0   0

  
  However, even after umount-ing the /mnt off of /dev/vdb, the zpool create 
command still fails:

  # zpool create -f lxd /dev/vdb
  /dev/vdb is in use and contains a unknown filesystem.

  
  If the /etc/fstab is edited so that /dev/vdb is *never* mounted and then 
rebooted, then the zpool create command succeeds:

  # zpool list
  NAME   SIZE  ALLOC   FREE  EXPANDSZ   FRAGCAP  DEDUP  HEALTH  ALTROOT
  lxd   14.9G   106K  14.9G - 0% 0%  1.00x  ONLINE  -

  # zpool status lxd
pool: lxd
   state: ONLINE
scan: none requested
  config:

  NAMESTATE READ WRITE CKSUM
  lxd ONLINE   0 0 0
vdb   ONLINE   0 0 0

  errors: No known data errors

  Something odd is going on with cosmic (18.10) and the combination of
  lxd, zfs and the kernel

  lxd version: 3.6
  zfsutils-linux/cosmic,now 0.7.9-3ubuntu6
  Linux: 4.18.0-10-generic
