[Kernel-packages] [Bug 1577957] Re: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation)

[mich...@hinespot.com]

OK, after 3 days, even the most recent firmware still has this bug:
/lib/firmware/iwlwifi-7265D-21.ucode

I'm switching back to the 15.10 firmware which did NOT have this bug and
we'll see if it still crashes: /lib/firmware/iwlwifi-7265D-12.ucode

Title:
  Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd
  generation)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The stock firmware for this device /lib/firmware/iwlwifi-
  7265D-16.ucode is crashing.

  Downloading the latest firmware (/lib/firmware/iwlwifi-7265D-21.ucode)
  isn't supported by the existing iwlwifi driver, and so the driver
  likely needs to be upgraded (or downgraded as well
  (https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/backport-
  iwlwifi.git/?h=release/LinuxCore18).

  I can also confirm that wifi *did* work successfully on 15.10 before
  upgrading to 16.04, although the kernel module required frequent
  restarts due to this bug:
  https://bugs.launchpad.net/ubuntu/xenial/+source/linux/+bug/1570595

  
  A detailed message about the firmware crash is located in the attachment from 
dmesg output.

  Thanks.

[Kernel-packages] [Bug 1552551] Re: Dell CERC Adapter hangs temporarily until reset. REGRESSION

[Daniel A. Gauthier]

I have bisected the source of the bug, then took a brief attempt at a
fix, unfortunately the quickie fix failed (bad CONST definitions in an
.h file).  I thought perhaps it was some kind of memory region locking
error causing corruption, but it appears to be more complicated than
that.

The bad commit is b836439 - 4KB Sector Support.
The previous good commit is 2f5d1f7.

I'm having difficulty integrating this compiled kernel into my PXE
environment, hence the week long delay in posting this, unfortunately I
lowered my priority for the whole issue once I figured it was too late
to get anything into the new LTS release first run and it's been marked
as expired.  christopher.m.penalver said to mark as Confirmed, but I
don't know if I can do that myself, or if I can do anything at all at
this point other than post this info here for anyone who's interested.

If I do ever get time to look at the (significant) code changes for the
4K support, I'll post changes here as well?

Dan

(Serverset Northbridge?).
  The 14.04LTS with all updates (or not) works fine with a perfectly consistent 
throughput of 77MB/s (slowest HD=66MB/s), RAID5.
  15.10 has the hangs of 10-60 seconds, AND with newest updates as of 
26-FEB-2016.
  I have changed PCI interrupts around and moved card slots to minimize sharing 
and removed cards - repeatedly.
  All hard drives and cables have been thoroughly tested, but the drives are 
mixed: 1 of 66MB/s, 1 of 125 MB/s, and 3 of 100MB/s.
  The drives not only work perfectly in 14.04LTS, but all Windows versions and 
DOS/BIOS-INT 19 as well (0x13).
  I have tried all combinations of card RAID options Read ahead, Write cache, 
and other BIOS options.
  Relevant dmesg lines (these were consecutive):
  [ 1046.808027] aacraid: Host adapter abort request (4,0,0,0)
  [ 1046.808123] aacraid: Host adapter reset request. SCSI hang ?

  Regression: Kernel Update in 16.04 from last days renders nvidia

Status in shim:

Bug description:
  I am running Ubuntu 16.04 since at least four months, always with the
  nvidia proprietary drivers (installed from the repository). I used
  nvidia-361 for a while with no issues (and i need it for steam
  gaming). However, an update installed on my machine yesterday breaks
  the nvidia drivers. I tried purging the driver, rebooting and
  reinstalling and i tried a newer version for the ubuntu-drivers ppa.
  Nothing helps: With the nvidia driver installed, i get a low-
  resolution login screen, but cannot login due to missing 3d
  acceleration. Running on nouveau works fine.

  This seems very strange to since everything worked until this
  afternoon. Yesterday, i was happily playing games on steam, installed
  some updates and now, my graphics are broken.

[Kernel-packages] [Bug 1581249] Re: resume on dell xps 15 9550 fails

[Eugene San]

@arges I am also experiencing suspend issues on my XPS13 but before
opening a separate bug report I would like to check if our systems are
affected by the same bug.

Please check/confirm the following:

1. Is your system fails to resume or stuck during suspend? Please
suspend the system using system menu (instead of closing the LID) and
describe power-button light behavior. Is it turned off after 5-10
seconds?

2. Is there an external monitor? What happens if it's disconnected? (In
my case connecting/reconnecting the monitor after the system is booted
triggers the issues).

3. Is it a persistent behavior?

4. Is http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.10-xenial/
still broken? (It solved the problem on my system).

[Kernel-packages] [Bug 1574814] Re: ThunderX: soft lockup in cursor_timer_handler() Edit

[dann frazier]

I used ftrace to do some duration measuring of the timer function
fb_flashcursor(). I noticed several places where this timer takes around
98 ms to complete. This time seems to be due to multiple calls to
__memcpy_toio() in ast_dirty_update():

for (i = y; i <= y2; i++) {
/* assume equal stride for now */
src_offset = dst_offset = i * afbdev->afb.base.pitches[0] + (x 
* bpp);
memcpy_toio(bo->kmap.virtual + src_offset, afbdev->sysram + 
src_offset, (x2 - x + 1) * bpp);


My theory is that this is causing mod_timer() to block on the other CPU, 
resulting in the soft lockup.

Also - I built a custom d-i using pristine 4.6-rc7, and I am able to
easily reproduce this. I think the next step here is to report this to
upstream.

[Kernel-packages] [Bug 1580272] Re: i915-bpo crashes on external hdmi input

[Chris J Arges]

I've also tested this on 4.4.0-22 with i915 patches here:
http://koti.kapsi.fi/~tjaalton/skl/mst/
And the problem persists.

In addition I've tested a 4.6 mainline from 5/8 and the problem persists
there as well.

Here is the warning from the mainline kernel:

  PCI: hv: Add explicit barriers to config space accesspci/host-hv
  I'm trying to pass-through Broadcom BCM5720 NIC (Dell device 1f5b) on a
  Dell R720 server.  Everything works fine when the target VM has only one
  CPU, but SMP guests reboot when the NIC driver accesses PCI config space
  with hv_pcifront_read_config()/hv_pcifront_write_config().  The reboot
  appears to be induced by the hypervisor and no crash is observed.  Windows
  event logs are not helpful at all ('Virtual machine ... has quit
  unexpectedly').  The particular access point is always different and
  putting debug between them (printk/mdelay/...) moves the issue further
  away.  The server model affects the issue as well: on Dell R420 I'm able to
  pass-through BCM5720 NIC to SMP guests without issues.

  While I'm obviously failing to reveal the essence of the issue I was able
  to come up with a (possible) solution: if explicit barriers are added to
  hv_pcifront_read_config()/hv_pcifront_write_config() the issue goes away.
  The essential minimum is rmb() at the end on _hv_pcifront_read_config() and
  wmb() at the end of _hv_pcifront_write_config() but I'm not confident it
  will be sufficient for all hardware.  I suggest the following barriers:

  1) wmb()/mb() between choosing the function and writing to its space.
  2) mb() before releasing the spinlock in both _hv_pcifront_read_config()/
 _hv_pcifront_write_config() to ensure that consecutive reads/writes to
the space won't get re-ordered as drivers may count on that.

  Config space access is not supposed to be performance-critical so these
  explicit barriers should not cause any slowdown.

[Kernel-packages] [Bug 1581241] [NEW] bluetooth headset doesn't automatically configure for a2dp correctly (regression)

[Ethan Blanton]

Public bug reported:

I have a bluetooth headset capable of several modes of connection
(headset, handsfree, and a2dp).  In 15.10, once I had correctly
configured it for a2dp once, applications using pulseaudio could use it
freely each time it was connected to the machine.

In 16.04, upon connection, applications that attempt to use it appear to
hang waiting for something.  I have to fiddle with its settings (and
sorry I can't be more specific, but it's not clear to me exactly what
sequence fixes it; I change it to/from headset and A2DP in blueman a few
times, do the same in pavucontrol, etc., and at some point it starts
working) for several minutes to get it working in a2dp mode.  It appears
that after connection I can put it in headset mode and start playing to
it immediately, but of course the audio quality is horrible.

Once I've fiddled it into working, it works until disconnected, and upon
reconnect it behaves the same as before I fiddled it into submission:
a2dp connection, but clients accessing it hang.

Title:
  bluetooth headset doesn't automatically configure for a2dp correctly
  (regression)

Status in bluez package in Ubuntu:
  New

Bug description:
  I have a bluetooth headset capable of several modes of connection
  (headset, handsfree, and a2dp).  In 15.10, once I had correctly
  configured it for a2dp once, applications using pulseaudio could use
  it freely each time it was connected to the machine.

  In 16.04, upon connection, applications that attempt to use it appear
  to hang waiting for something.  I have to fiddle with its settings
  (and sorry I can't be more specific, but it's not clear to me exactly
  what sequence fixes it; I change it to/from headset and A2DP in
  blueman a few times, do the same in pavucontrol, etc., and at some
  point it starts working) for several minutes to get it working in a2dp
  mode.  It appears that after connection I can put it in headset mode
  and start playing to it immediately, but of course the audio quality
  is horrible.

  Once I've fiddled it into working, it works until disconnected, and
  upon reconnect it behaves the same as before I fiddled it into
  submission: a2dp connection, but clients accessing it hang.

Bug description:
  Hi,

  Since updating to 16.04 with kernel vmlinuz-4.4.0-22-generic my laptop
  no longer completes the boot sequence under a normal boot scenario -
  the "loading initrd..." message is displayed, then, when the VGA
  modesetting usually kicks the display into a higher resolution, the
  screen blanks and the startup apparently halts. This is a regression
  from 4.2 series kernels. I can successfully bring up the system if I
  revert to 4.2.0-35, and also if I boot  4.4 with the failsafe setting
  (but then X is painfully slow, as its using software)

[Dave Brown]

Being the tired and daft bugger that I am, I failed to convert minutes
and seconds to frames properly resulting in trying to consume several
hours worth of PCM data per track.  Not my brightest moment and I would
like to apologise for wasting your time...

  Kernel Oops - unable to handle kernel NULL pointer dereference at
  0002; IP is at  mmc_ioctl_cdrom_read_audio+0x212/0x3b0

Status in linux package in Ubuntu:
  Invalid

Bug description:
  While playing around with the CDROM API found in linux/cdrom.h I
  encountered a kernel oops when my program stalls.  My code can be
  found at https://github.com/bigdavedev/audiorip.

  My program simply examines the ToC and then begins reading the PCM
  data track-by-track.  I would expect it to complete without any major
  issue

  At first I assumed it was the CD, but after switching CDs several
  times I noticed that the oops happens at around frame 170925, reading
  CD_FRAMES (75) per ioctl.  At this point, the disc is spinning at full
  speed.  I have not yet tried reading fewer frames, nor have I tried
  setting the speed to something not max to see if I still receive a
  kernel oops.  This would not be problematic to try.

  I have attached the output from `ubuntu-bug linux` to this issue.

There's also a couple other SMBIOS 3.0 related fixes that is listed as
recomended for 3.0 on http://dmidecode.nongnu.org/

Fix 'No SMBIOS nor DMI entry point found' on SMBIOS3
http://git.savannah.gnu.org/cgit/dmidecode.git/commit/?id=bf7bad24ce141dab5b5acc3ffb98ce5fe4a8e0f9

[Kernel-packages] [Bug 1568830] Re: make_request bug: can't convert block across chunks or bigger than 512k 2554601336 124

[Brian J. Murrell]

> 3.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/

This one works.

I've got to say that it's really annoying that every time I reboot my
system comes back with a degraded array:

# cat /proc/mdstat 
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] 
[raid10] 
md1 : active raid0 sdc[1] sdb[0]
  1953524736 blocks super 1.2 512k chunks
  
md0 : active raid1 sdd[0]
  1953514496 blocks [2/1] [U_]
  
unused devices: 

Before reboot it looked like this:

# cat /proc/mdstat 
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] 
[raid10] 
md1 : active raid0 sdb[0] sdc[1]
  1953524736 blocks super 1.2 512k chunks
  
md0 : active raid1 md1[1] sdd[0]
  1953514496 blocks [2/2] [UU]
  
unused devices:

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Timo Aaltonen]

I still need test results from my kernel build, since that has what is
going to be in the next SRU kernel and if it's still broken then there's
something to be backported to core-drm (from v4.4..v4.6)

  Plugging HDMI screen in causes system hang

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1510344] Re: Keyboard Backlight Turns on at boot

[Sebastien Bacher]

@Mario, thanks for testing the fix! I'm going to upload/SRU that one to
start then. Could you run unity-settings-daemon with --debug and share
the log? it might give an hint on what is happening with the other issue

[Kernel-packages] [Bug 1510344] Re: Keyboard Backlight Turns on at boot

[Mario Limonciello]

Well there are really two problems here as I understand it.
I can however confirm that that the first problem (backlight turns on on it's 
own at boot) is fixed by this patch.  So that's a definite improvement.

The second problem (backlight turns on on it's own after unlock) I can still 
reproduce.  Here is my reproduce scenario.
1) Install patched u-s-d from patch in #55.
2) Turn on backlight with hotkey.
3) Shutdown machine.
4) Turn on machine.
5) Log in.
6) Turn off backlight with hotkey.
7) Lock machine (ctrl-alt-l), wait for screensaver to kick in.
8) unlock machine
9) Notice that backlight turned back on.

Alas, the exact same result on the exact same frame in the upstream

  Kernel Oops - unable to handle kernel NULL pointer dereference at
  0002; IP is at  mmc_ioctl_cdrom_read_audio+0x212/0x3b0

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  While playing around with the CDROM API found in linux/cdrom.h I
  encountered a kernel oops when my program stalls.  My code can be
  found at https://github.com/bigdavedev/audiorip.

  My program simply examines the ToC and then begins reading the PCM
  data track-by-track.  I would expect it to complete without any major
  issue

  At first I assumed it was the CD, but after switching CDs several
  times I noticed that the oops happens at around frame 170925, reading
  CD_FRAMES (75) per ioctl.  At this point, the disc is spinning at full
  speed.  I have not yet tried reading fewer frames, nor have I tried
  setting the speed to something not max to see if I still receive a
  kernel oops.  This would not be problematic to try.

  I have attached the output from `ubuntu-bug linux` to this issue.

  Broadwell ECRC Support missing in Ubuntu

Bug description:
  Here is the problem statement from the Dell team:

  When booting into Ubuntu 14.04.4 with a Broadwell CPU and an Intel
  Quick Assist Card, the memory location that corresponds to ECRC is set
  to 0x01e0, when the BIOS is setting this location 0x00a0 pre-OS boot.
  This causes the card to not function unless we implement the following
  workaround using setpci.

  “setpci –s AA:BB.C 160.w=0”, where AA:BB.C is the PCI Root Path for
  the Intel Quick Assit Card.

  We’ve verified the memory location is correct when booting to other
  OSes, such as RHEL 7.2 and Windows Server 2012 R2.

  If there is any information you can give as to why this may be
  occurring in Ubuntu or where we may start to debug when the memory is
  changed, we would appreciate it.

I have tested against both 4.4.0-21.37 and 4.4.0-22.39 on two laptops
with the same results.

I will test with an upstream kernel and get back to you.

Bug description:
  While playing around with the CDROM API found in linux/cdrom.h I
  encountered a kernel oops when my program stalls.  My code can be
  found at https://github.com/bigdavedev/audiorip.

  My program simply examines the ToC and then begins reading the PCM
  data track-by-track.  I would expect it to complete without any major
  issue

  At first I assumed it was the CD, but after switching CDs several
  times I noticed that the oops happens at around frame 170925, reading
  CD_FRAMES (75) per ioctl.  At this point, the disc is spinning at full
  speed.  I have not yet tried reading fewer frames, nor have I tried
  setting the speed to something not max to see if I still receive a
  kernel oops.  This would not be problematic to try.

  I have attached the output from `ubuntu-bug linux` to this issue.

[Kernel-packages] [Bug 1581169] Re: kernel panic (General protection fault) on module hpsa (lockup_detected)

[Eric Desrochers]

Hi Brad,

I do have a vmcore + dmesg, but this is very large (total: ~16GB).

I will provide the test kernel based on Ubuntu-lts-4.2.0-36.41_14.04.1
including commit "fb53c43" and ask my contact to test it and confirm if
it mitigate the issue on their affected systems where they can reproduce
the panic on demand using the "udevadm" command.

Bug description:
  it has been brought to my attention the following:

  Kernel version: 4.2.0-30-generic #36~14.04.1-Ubuntu

  When running an sosreport on HP DL380 gen8 machines running this
  kernel (Ubuntu 14.04.4 using linux-generic-lts-wily), which includes
  hpsa 3.4.10-0, hspa causes a kernel panic when sosreport is scanning
  block devices. These are machines with an onboard p420i and
  daughtercard p420 RAID controller, with each drive in a single raid0
  configuration. (unideal, but the machines do not boot when the card is
  in HBA mode).

  This panic does not happen on kernel 3.13 with hpsa 3.4.1-0 when using
  sosreport.

  The funny thing is kernel 4.2 / 3.4.10-0 still is a more stable
  solution - I have yet to see a prior issue in which the p420 would
  lock up on this version. One issue wit h this is HP 99% of the time
  will require an sosreport when we raise any hardware issues. I can no
  longer produce that on kernel 4.2 machines because they kernel panic.

  I can reproduce this consistently with several other machines in our
  environment. - please let me know if you would like more info.

[Kernel-packages] [Bug 1580345] Re: LG 22V240 all in one PC with ACPI problems

[Vicente Jiménez Aguilar]

Sorry for the delay, this was not my computer but Marta's one.

This computer was bought recently and installed directly with Ubuntu 16.04 in 
dual boot with Windows.
So no previous kernel version was tested.
Even Ubuntu 16.04 CD install media needed kernel parameter acpi=off to boot.

I just tried kernel 4.6 rc7 and problem persist.
I had also tried upstream kernel version 4.5 with the same results.

Only with acpi=off the system is usable.

Any other option:
Lot of
NMI watchdog: Watchdog detected Hard LOCKUP on cpu 0
other CPU numbers also seen.
System present LightDM after more than 15min.
Desktop not usable due to constant lock-up (detected because mouse pointer and 
user name input stop blinking)
Does not had the patience to try to log in after waiting more than 20 minutes.

Title:
  LG 22V240 all in one PC with ACPI problems

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have the following problem with a LG all in one PC V220.
  Ubuntu 16.04 does not boots unless ACPI is deactivated with acpi=off kernel 
option.
  Never see the X starting after waiting a lot of minutes.
  Removing the quiet kernel parameter we can see the kernel reporting a lot of 
errors and progressing very slowly.

  None of those parameters allowed a normal boot:
  acpi=ht
  pci=noacpi
  acpi=noirq
  pnpacpi=off
  noapic
  nolapic

  Only acpi=off allowed the system to boot.
  But with very poor performance and only one core CPU.

  Tested also latest vanilla linux kernel with same problem.

  Hardware information in attached files.
  Attached ACPI dump extracted from Windows.

  I have some experience with many GNU/Linux distros but no experience 
debugging ACPI.
  I am willing to help debug this issue.
  Tell what you need.

[Kernel-packages] [Bug 1498667] Re: [Toshiba P50W-B00F] Touchscreen no longer working

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
c0d96af2e0427cc90b1f0d3c6a5294d90f93fcf4

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1498667

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

  kernel panic (General protection fault) on module hpsa

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  it has been brought to my attention the following:

  Kernel version: 4.2.0-30-generic #36~14.04.1-Ubuntu

  When running an sosreport on HP DL380 gen8 machines running this
  kernel (Ubuntu 14.04.4 using linux-generic-lts-wily), which includes
  hpsa 3.4.10-0, hspa causes a kernel panic when sosreport is scanning
  block devices. These are machines with an onboard p420i and
  daughtercard p420 RAID controller, with each drive in a single raid0
  configuration. (unideal, but the machines do not boot when the card is
  in HBA mode).

  This panic does not happen on kernel 3.13 with hpsa 3.4.1-0 when using
  sosreport.

  The funny thing is kernel 4.2 / 3.4.10-0 still is a more stable
  solution - I have yet to see a prior issue in which the p420 would
  lock up on this version. One issue wit h this is HP 99% of the time
  will require an sosreport when we raise any hardware issues. I can no
  longer produce that on kernel 4.2 machines because they kernel panic.

  I can reproduce this consistently with several other machines in our
  environment. - please let me know if you would like more info.

[Kernel-packages] [Bug 1581005] Re: Dell XPS 15 9550 Freezes when HDMI is plugged in

[Joseph Salisbury]

I'd like to test some of the 4.6 release candidates.  The all can be downloaded 
from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/

We should first test v4.6-rc1:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc1-wily/

If the bug still exists in -rc1, maybe try -rc4 and then newer versions
until we find the last bad kernel and first good one.  We can then
bisect between those two versions:

v4.6-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc4-wily/
v4.6-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc6-wily/

  There are, of course, a number of sauce items already present in
  Ubuntu to keep. Please add the following additional sauce item for
  networking performance [attached].

  This rebase request is intended for wily/15.10. We should investigate
  it's applicability to vivid/15.04 and HWE kernels as well. Because
  14.04's HWE kernel will change to wily in January, 15.10 may be
  sufficient in the long term. Thank you!

Title:
  kernel panic (General protection fault) on module hpsa
  (lockup_detected)

Status in linux package in Ubuntu:

Bug description:
  it has been brought to my attention the following:

  Kernel version: 4.2.0-30-generic #36~14.04.1-Ubuntu

  When running an sosreport on HP DL380 gen8 machines running this
  kernel (Ubuntu 14.04.4 using linux-generic-lts-wily), which includes
  hpsa 3.4.10-0, hspa causes a kernel panic when sosreport is scanning
  block devices. These are machines with an onboard p420i and
  daughtercard p420 RAID controller, with each drive in a single raid0
  configuration. (unideal, but the machines do not boot when the card is
  in HBA mode).

  This panic does not happen on kernel 3.13 with hpsa 3.4.1-0 when using
  sosreport.

  The funny thing is kernel 4.2 / 3.4.10-0 still is a more stable
  solution - I have yet to see a prior issue in which the p420 would
  lock up on this version. One issue wit h this is HP 99% of the time
  will require an sosreport when we raise any hardware issues. I can no
  longer produce that on kernel 4.2 machines because they kernel panic.

  I can reproduce this consistently with several other machines in our
  environment. - please let me know if you would like more info.

  Please rebase Hyper-V support to the final upstream 4.3 kernel.

  The following files and directories contain Hyper-V support:
  arch/x86/include/asm/mshyperv.h
  arch/x86/include/uapi/asm/hyperv.h
  arch/x86/kernel/cpu/mshyperv.c

  include/linux/hyperv.h
  tools/hv/

  There are, of course, a number of sauce items already present in
  Ubuntu to keep. Please add the following additional sauce item for
  networking performance [attached].

  This rebase request is intended for wily/15.10. We should investigate
  it's applicability to vivid/15.04 and HWE kernels as well. Because
  14.04's HWE kernel will change to wily in January, 15.10 may be
  sufficient in the long term. Thank you!

  I have a Lenovo B5400 laptop with RTL8723BE wireless module. Using 802.11n 
the internet connection constantly getting lost after a random duration 
(usually after 20-30 minutes). The NetworkManager applet does not recognize it 
(still looks like i have a connection), but when I try do disconnect and 
connect again, there is only one useful information I can find in dmesg:
  "wlan0: deauthenticating from [ap mac address] by local choice (Reason: 
3=DEAUTH_LEAVING)"
  Reinserting the driver (modprobe -r rtl8723be and modprobe rtl8723) used to 
be my only workaround, but it does not work anymore and now I have to reboot.

  Switching to 802.11g (54Mb/s) shows a small performance improvement
  while browsing websites. However there are still random "ping jumps"
  and the connection still drops (maybe 1-2 minutes later than usual at
  least).

  The following improves performance, but I am still encountering some minor 
performance issues while playing online games (random lag spikes):
  sudo nano /etc/modprobe.d/rtl8723be.conf

[Kernel-packages] [Bug 1571798] Re: Broadwell ECRC Support missing in Ubuntu

[Joseph Salisbury]

Thanks for testing, John.  To narrow it down further, can you test some
of the 3.18 release candidates?

They can all be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/

I'd suggest trying -rc1 first.  If that version does not have the bug,
try some of the newer candidates:

v3.18-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc1-utopic/
v3.18-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc4-vivid/
v3.18-rc7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc7-vivid/

Once we know the last good kernel version and the first bad one, we can
bisect between them.

  Here is the problem statement from the Dell team:

  When booting into Ubuntu 14.04.4 with a Broadwell CPU and an Intel
  Quick Assist Card, the memory location that corresponds to ECRC is set
  to 0x01e0, when the BIOS is setting this location 0x00a0 pre-OS boot.
  This causes the card to not function unless we implement the following
  workaround using setpci.

  “setpci –s AA:BB.C 160.w=0”, where AA:BB.C is the PCI Root Path for
  the Intel Quick Assit Card.

  We’ve verified the memory location is correct when booting to other
  OSes, such as RHEL 7.2 and Windows Server 2012 R2.

  If there is any information you can give as to why this may be
  occurring in Ubuntu or where we may start to debug when the memory is
  changed, we would appreciate it.

We can confirm this is the last line we see regardless of the disk:

On a working disk the next line is :

"ATTRS{lockup_detected}"


It seems to stuck at the lockup_detected attribute.

  [Xenial] net: updates to ethtool and virtio_net for speed/duplex
  support

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  Post 4.4, several changes landed upsteam to allow users to set interface
  speed for virtio_net backed devices.  This feature is extremely useful
  for those doing large-scale networking simulations where Ubuntu-based
  VMs are used to simulate hosts.  Not only does it allow hosts to report
  the same speed in simulations for monitoring tools, but it is required
  to simulate 802.3ad bonding where link-speed is reported to the peer
  device.  Without proper speed setting there are cases where establishing
  LACP adjacency is not possible.  

  After this patch setting the link speed and duplex now works just as one would
  expect.  I'm running the kernel that contains this patch for these commands:

  $ sudo ethtool -s enp0s8 speed 10 duplex full 
  $ sudo ethtool enp0s8
  Settings for enp0s8:
Supported ports: [ ]
Supported link modes:   Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Advertised link modes:  Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: 10Mb/s
Duplex: Full
Port: Other
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Link detected: yes

  I've already submitted patches to the kernel-team mailing list.  Those
  patches can be found in this thread: https://lists.ubuntu.com/archives

[Kernel-packages] [Bug 1578022] Re: dmidecode fails to output smibios 3.0 info

[Andre Tomt]

Recent BIOS upgrades from Asrock Rack is also hitting this, for example
v2.10 for the dual socket Xeon EP2C612D16-2L2T board.

For Asrock at least SMBIOS 3.0 seems to have arrived with Broadwell-EP
CPU support (Xeon E5 v4).

  Hi,

  For checkpoint restore support via CRIU, we need to use the following
  modules:

  udp_diag
  tcp_diag
  inet_diag
  netlink_diag
  af_packet_diag
  unix_diag

  some of which aren't included in linux-image, requiring users to
  install linux-image-extra. It would be handy if these were in the main
  kernel package.

  But with very poor performance and only one core CPU.

  Tested also latest vanilla linux kernel with same problem.

Title:
  LG V220 all in one PC with ACPI problems

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have the following problem with a LG all in one PC V220.
  Ubuntu 16.04 does not boots unless ACPI is deactivated with acpi=off kernel 
option.
  Never see the X starting after waiting a lot of minutes.
  Removing the quiet kernel parameter we can see the kernel reporting a lot of 
errors and progressing very slowly.

  None of those parameters allowed a normal boot:
  acpi=ht
  pci=noacpi
  acpi=noirq
  pnpacpi=off
  noapic
  nolapic

  Only acpi=off allowed the system to boot.
  But with very poor performance and only one core CPU.

Scratch my last comment. I'll add some screenshots with the issue
(hovering the mouse on top of unrendered text shows it temporarily).

After that I'll try to bump my kernel, but will need some days of
testing to reproduce problem

  Suspend breaks on gnome session not on unity session - dell xps 14z

Status in linux package in Ubuntu:

Bug description:
  I've got two users on this computer. When using gnome 3 session the
  suspend behaves really quirky. After suspend it might have rendering
  problems or it doesn't come back or it comes back with a very slow
  response afterwards.

  In Unity the problem doesn't appear, so a hardware problem seems to
  not affect this other software.

  I'll try to make a screenshot of the rendering problem

  FCP devices are not detected correctly nor deterministically

Bug description:
  Release notes:
  Usage of SCSI LUNs on DS8870 Storage server with μCode Bundles 87.51.xx.0 
(LMC 7.7.51.xx) via NPIV enabled zfcp adaptors causes detection issues. LP 
#1567602 In that case do not use NPIV enabled zfcp adaptors.


  
  Scenario:
  Using Installer 432.
  No DASD devices, just two FCP CHPIDs with two LUNs each (configured for 
NPIV), provided via parmfile.
  I expect the installer to probe and detect the LUNs automatically once I 
enable the FCP CHPIDs.

  Repeated five times, I got different results each time. Detected LUNs
  vary between 2 and 4. One time 3 LUNs appear on SCSI1 and one on SCSI2
  which looks especially odd to me.

  Subsequent steps to create partitions and file systems in the
  installer fail.

  Following is one of the five cases with more details:
  After enabling CHPID 192b:

  Next, the installer warns that no disk drives were detected.

  I checked this on a system (installer 445) with two NPIV enabled FCP
  devices that have 4 LUNS each. I only get the first of four LUNs per
  adaptor:

  [Xenial] net: updates to ethtool and virtio_net for speed/duplex
  support

Status in linux package in Ubuntu:

Status in linux source package in Xenial:
  Incomplete

Bug description:
  Post 4.4, several changes landed upsteam to allow users to set interface
  speed for virtio_net backed devices.  This feature is extremely useful
  for those doing large-scale networking simulations where Ubuntu-based
  VMs are used to simulate hosts.  Not only does it allow hosts to report
  the same speed in simulations for monitoring tools, but it is required
  to simulate 802.3ad bonding where link-speed is reported to the peer
  device.  Without proper speed setting there are cases where establishing
  LACP adjacency is not possible.  

  After this patch setting the link speed and duplex now works just as one would
  expect.  I'm running the kernel that contains this patch for these commands:

  $ sudo ethtool -s enp0s8 speed 10 duplex full 
  $ sudo ethtool enp0s8
  Settings for enp0s8:
Supported ports: [ ]
Supported link modes:   Not reported

[Kernel-packages] [Bug 1581132] Re: [Xenial] net: updates to ethtool and virtio_net for speed/duplex support

[Andy Gospodarek]

Brad, this isn't really a bug, but a feature request.

Before my patches, it was not possible to get or set link speed on a
virtio_net backed device.

$ sudo ethtool enp0s8 
Settings for enp0s8:
Link detected: yes
$ sudo ethtool -s enp0s8 speed 10 duplex full 
Cannot get current device settings: Operation not supported
  not setting speed
  not setting duplex
$ ethtool -i enp0s8 
driver: virtio_net
version: 1.0.0
firmware-version: 
expansion-rom-version: 
bus-info: :00:08.0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

As demonstrated in my description this is now possible.
