Bug#1033050: amdgpu output on USB-C docking station fails (after screen suspend?)

2023-03-16 Thread Bernhard Schmidt
Package: src:linux
Version: 6.1.15-1
Severity: important

Hi,

I run a Lenovo T14s Gen2 with a Lenovo Dockingstation and two
DP-connected external displays, with KDE on Wayland.

Every few days, after an extended coffee break/lunch, I find my
previously locked session unusable. The displays stay in standby mode,
although KDE thinks they are connected and extends the workspace there.

The quickest option at this point is to open the laptop lid, switch to
the console and reboot. I have not found a way to revive the external
displays.

There is one kernel WARNING that looks related to external MST displays,
happens at the right time and matches my perceived frequency. KDE energy
settings are currently set to

blank screen after 5 minutes
suspend screen after 10 minutes

I left the desktop at 11:13, so the kernel warning happens at the same
time the screen was suspended.

I've tried your kernel on a R740 with Buster userland (I did not find
an easy way to build a new Stretch debian-installer image with the
updated kernel) and it works just fine.

Hi Karsten,

Thanks for the test. Can you check whether numa=off on the kernel command line 
fixes this as well?

Bug#883938: Workaround available

2017-12-11 Thread Bernhard Schmidt
Control: summary -1 Seems two affect machines with more than one socket. 
Workaround: set maxcpus=1 on the kernel command line

Hi,

this seems to affect two-socket boxes.

Workaround is to set maxcpus=1 on the kernel command line.

Bug#816377: Additional Info

2016-03-01 Thread Bernhard Schmidt
The issue affects SLES11SP4 (3.0.101-68-default) and SLES12SP1
(3.12.53-60.30-default) as well. Both have backported vmxnet3 1.4.2.0-k
in their kernel package.

It does _not_ affect the official vmxnet3 module from the VMware tools,
also calling itself version 1.4.2.0. So there seems to be a difference
between the in-tree and the out-of-tree module.



Bug#816377: vmxnet3 LRO IPv6 performance issues (stalling TCP)

2016-03-01 Thread Bernhard Schmidt
Package: src:linux 
Version: 3.16.7-ckt20-1+deb8u3
Severity: normal

Hi,

short history on this:

We run a pretty large VMware infrastructure. In November 2014 we migrated the
hardware the cluster runs on

Old: HP BL490c Gen6, Flex10 something, BCM57711E
New: HP BL460c Gen8, HP FlexFabric 630FLB, BCM57840

We immediately saw huge performance issues with TCPv6 connections (to the point
of being absolutely unusable even for basic tasks) on machines that had already
migrated to the new hardware. Migrating the machine back to the old hardware
immediately fixed the issue.

This was eventually traced down to vmxnet3 enabled Linux VMs with "old"
drivers, in this case Debian Wheezy with vmxnet3 1.1.19, having issues with
LROv6. Apparently the new NIC chipset in the host supports LROv6, while the old
one didn't. Disabling LRO fixed the issue.

Back then neither the vmxnet3 module from the official VMware-Tools (1.1.35)
nor the in-kernel version in Testing/Jessie (1.2.0.0) exhibited the problem, so
it was decided to run the Wheezy systems with the official VMware module and
keep the in-kernel module for Jessie.

Fast Forward:

Lately we have received reports about this issue resurfacing on Jessie systems.
Or normal workload does not seem to be affected that bad, but we have
identified two tasks where it is easily reproducible

 - Inbound Debian mirror sync (rsync from syncproxy.eu) over IPv6
 - iperf3 IPv6 towards a virtual machine (server on the VM).

Disabling LRO fixes the issue.

Can you test the fix in Bug#714929 (vmwgfx.enable_fbdev=1 on the kernel
command line)?

Even directly in front of the console I can't make out any error
message, and if I change the filename to something non-existant I get
a error message and have to press a key to continue.

 We still have the snapshot available, if you have an idea

Should I be able to see that somehow (xfs_info from a rescue system or
something like that)? Doesn't xfs log anything when it replays the log
(I know ext4 does, but I don't recall seeing that for XFS ever)

The system is normally rebooted using /sbin/reboot soon after
dist-upgrade is finished. There are no errors and our customizations
don't touch the reboot part at all. If there was a problem with
unclean shutdown it would be a common error, we are seeing ~20%
failure rates on upgrades.

If I understand you correctly since grub isn't erroring out on the
initrd filename it is likely there on disk, but an out-of-date
version. I recall the initrd being generated twice, so maybe the file
that is on the disk (read by grub) is somehow incomplete and the first
boot syncs the updated image from journal to disk. Or maybe it is
really unreadable ... other guess would be a corruption that can be
replayed by 3.2.0, but not by 3.16.0 (seems unlikely)

If I mount the filesystem in a rescue system with norecovery and the
initrd is either different or missing that would narrow it down, no?
And a workaround would be calling "sync" before the reboot.

I don't have access to the snapshot until Monday, but I don't think it
will help. As you can see in the video a simple fsck/mount in initrd in
the old kernel is enough, and grub isn't touched there.

But I'll test on Monday to be sure.

Got another system with the symptoms and managed to get a snapshot.

It is really extremely weird. The kernel output is

List of all partitions:
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)

This is reproducible. To fix it it is enough to boot into the Wheezy
kernel (even with init=/bin/sh), then reboot. It apparently does
something to the root-fs (fsck?) which allows the Jessie kernel to boot.

I have asked our Windows guys to make a screencast, it is uploaded here.

Thanks for the feedback.

Standard grub2 installation, nothing special about it. Grub did not
print any errors about not finding a file and I only ran
update-initramfs and rebooted.

I hope the next time it happens it will be with a less critical
machine and I can keep it down a bit to debug further.

Bernhard

Bug#783620: initramfs-tools: initramfs broken on first boot into Jessie, "Unable to mount root fs on unknown-block(0, 0)"

2015-04-28 Thread Bernhard Schmidt
Package: initramfs-tools
Version: 0.120
Severity: important

Dear Maintainer,

I have a hard time wrapping my head around this bug, feel free to assign 
somewhere
else.

We have started upgrading some of our production VMs to Jessie. The testsystems 
worked
fine, but I have hit the following bug for the second time on a production VM 
now.

- dist-upgrade works flawlessly
- on first boot into Jessie I get an immediate (<1s) kernel-panic (see attached
  screenshot) about being unable to find the root fs. Unfortunately I'm unable 
to
  get the full boot log, since I don't have a serial console there and kernel
  messages scroll by too fast.
- To fix the issue I have to boot into the old Wheezy kernel (3.2.0-4-amd64) in
  grub and regenerate the initrd for the Jessie kernel

# update-initramfs -k 3.16.0-4-amd64 -u

  Then it works fine.

Now comes the interesting part ... I have saved the broken initrd for later 
analysis

The compressed size is marginally different (broken being 3k smaller)

-rw-r--r--  1 root root 14339199 Apr 28 13:59 initrd.img-3.16.0-4-amd64
-rw-r--r--  1 root root 14338898 Apr 28 13:58 initrd.img-3.16.0-4-amd64.broken

The uncompressed size is the same

root@lxmhs63:/tmp# zcat /boot/initrd.img-3.16.0-4-amd64.broken > 
initrd.img-3.16.0-4-amd64.broken
root@lxmhs63:/tmp# zcat /boot/initrd.img-3.16.0-4-amd64.broken >

-rw-r--r-- 1 root root 45304832 Apr 28 14:44 
/tmp/initrd.img-3.16.0-4-amd64.broken

The checksum is different

root@lxmhs63:/tmp# md5sum /tmp/initrd.img-3.16.0-4-amd64*
7b24aa901b697dc5dfdbad03bd199072  /tmp/initrd.img-3.16.0-4-amd64
5e467c0a49afa4ddae315cc6e818d7ac  /tmp/initrd.img-3.16.0-4-amd64.broken

Now comes the puzzling part ... the _content_ of the initrd is exactly the same

root@lxmhs63:/tmp# mkdir broken && cd broken && cpio -id < 
../initrd.img-3.16.0-4-amd64.broken  
88486 blocks
root@lxmhs63:/tmp/broken# cd ..
root@lxmhs63:/tmp# mkdir ok && cd ok && cpio -id < ../initrd.img-3.16.0-4-amd64 

88486 blocks
root@lxmhs63:/tmp/ok# cd ..
root@lxmhs63:/tmp# diff -urN broken ok

I will try to capture a screenlog on the next upgrades, maybe there is 
something 
interesting in there.

Hi,

This still affects Jessie, I can easily reproduce it.

This bug makes it impossible to access the console of a VM without booting it 
and adjusting 
the kernel commandline, so I think this warrants a classification as important.

Bug#714868: tgt: New versions supports rbd backend (Ceph Rados Block storage)

2014-03-23 Thread Bernhard Schmidt
Package: tgt
Followup-For: Bug #714868

Hi,

Looks like Ubuntu has started updating tgt on their own, including new
upstream versions and enabling RBD.

It would be great if Debian could import the Ubuntu changes on this one,
or maybe James Page (who seems to be maintaining it in Ubuntu) could take
it over. There does not seem to be much interest on the Debian side of 
things.

Bug#734204: linux-image-3.2.0-4-486: Please set CONFIG_ALIX and CONFIG_LEDS_GPIO

2014-01-04 Thread Bernhard Schmidt
Package: linux-image-3.2.0-4-486
Version: 3.2.51-1
Severity: wishlist

Hi,

please set the config options CONFIG_ALIX and CONFIG_LEDS_GPIO. They are not
set in both current stable and current testing kernels and are required to
control the GPIO LED in PCEngines ALIX boards. From the kernel config:

config ALIX
bool "PCEngines ALIX System Support (LED setup)"
select GPIOLIB
---help---
  This option enables system support for the PCEngines ALIX.
  At present this just sets up LEDs for GPIO control on
  ALIX2/3/6 boards.  However, other system specific setup should
  get added here.

  Note: You must still enable the drivers for GPIO and LED support
  (GPIO_CS5535 & LEDS_GPIO) to actually use the LEDs

  Note: You have to set alix.force=1 for boards with Award BIOS.

Setting these in the i386 flavour is most likely enough, there are no
64bit capable Geode processos out there.

This may help to get rid of the orphaned package src:leds-alix in sid,
see http://packages.qa.debian.org/l/leds-alix.html

Regards,
Bernhard

Bug#714929: linux-image-3.9-1-amd64: vmwgfx freezes console with gfx_payload

2013-07-25 Thread Bernhard Schmidt
Package: src:linux
Followup-For: Bug #714929

Some more information.

- It still happens with 3.10-1-amd64 (3.10.1-1) from sid
- Workaround is (next to blacklisting) setting vmwgfx.enable_fbdev=1
  on the kernel commandline, which is probably the same as setting the 
  kernel config option CONFIG_DRM_VMWGFX_FBCON
  - !! When the machine has once successfully booted with enable_fbdev=1,
!! soft reboots (Ctrl-Alt-Del or /sbin/reboot) do not lock up the
!! console!
  - the fix does not survive hard reset of the VM or powering it down

So I think just setting CONFIG_DRM_VMWGFX_FBCON would help, unless that 
option is dangerous somehow.

Best Regards,
Bernhard

Re: Bug#702452: linux-image-3.8-trunk-amd64: LVM volume groups are not found, volumes not activated

2013-03-06 Thread Bernhard Schmidt

Hello Ben,


Package: src:linux
Version: 3.8-1~experimental.1
Severity: normal

My / is on a LVM volume. Kernel 3.8 logs 'Volume group "ssd" not found'
and "/dev/mapper/ssd-debian not found" on startup


These messages do not come from the kernel.  LVM2 is a userland thing;
the kernel only provides the building blocks for it (device-mapper).


and drops me in the
initramfs shell. The LVM pv, vg and lv are visible in lvm just fine, but
the logical volume is not activated and thus not accessible to the
system.

(initramfs) lvm
lvm>  lvchange -a y ssd/debian

fixes the problem.

This works fine in 3.2.0-4 and 3.7-trunk. initrd has the same timestamp
for both 3.7 and 3.8.

[...]

I suspect this may be due to a difference in timing of device
initialisation.  AFAIK initramfs-tools still doesn't know how
to handle asynchronous device discovery and relies on you to
fudge it with the 'rootdelay' parameter.


Yeah, looks like. Even rootdelay=1 seems to be enough to fix it.

Since there are a couple of bugs filed with initramfs-tools already I'm 
marking this bug done.


Thanks for your quick response.

Bernhard

Looks good, VMware is detected, together with the patch from #699913
memory hotplugging works fine.

That works fine, thanks! Can this somehow be patched in the kernel or
shall we just change our boot parameters?

Hello Ben,


Squeeze is another story, but I think there is another problem as well.
Previously we sometimes saw the backtrace, sometimes just the following
message.

This is 'invalid argument' - wonder where that's coming from?

We did not observe the backtrace anymore, but the "driver data not
found" is still there.

So I think the patch fixes the backtrace (allocation error) on both
squeeze and wheezy, but squeeze has a second issue. I'll go through the
bug reports and open a new one.


Right, this is definitely a separate bug.


I finally found an article that describes this behaviour. Turns out that 
when this message appears, hotplug does not fail completely, but one 
memory bank (128MB) is missing.


http://communities.vmware.com/message/1299666#1299666

I have opened Bug #700544 for this, it only seems to affect Squeeze. 
Don't know whether it is worth fixing that, the patch is more than a few 
lines and Squeeze will hopefully be oldstable soon.

It looks good on Wheezy now. Hard to tell for sure because it did not
always happen, especially not with freshly booted devices, but we did
install the kernel on a few Wheezy boxes and put load on them, and I did
not observe the backtrace anymore.

Squeeze is another story, but I think there is another problem as well.
Previously we sometimes saw the backtrace, sometimes just the following
message.


[   44.22] VMCIUtil: Updating context id from 0x7a3c21d6 to
0x7a3c21d6 on event 0.

We did not observe the backtrace anymore, but the "driver data not
found" is still there.

So I think the patch fixes the backtrace (allocation error) on both
squeeze and wheezy, but squeeze has a second issue. I'll go through the
bug reports and open a new one.

Hello,

thanks will do. Your description fits quite well, we've been unable to
reproduce with a freshly booted system even in production, but most VMs
that were upgraded due to memory shortage failed.

Bug#600957: linux-image-2.6.32-5-amd64: Please include vmw_pvscsi (VMware PVSCSI)

Hi,

vmw_pvscsi module from 2.6.33 mainline to get full access to the (faster)
paravirtualized VMware SCSI controller.
