Description Krzysztof Chmielewski 2023-07-19 16:32:12 UTC

After applaying latest kernel updates:

openSUSE-SLE-15.5-2023-2871 - Security update for the Linux Kernel

Linux version 5.14.21-150500.55.7-default (geeko@buildhost) (gcc (SUSE Linux) 7.5.0, GNU ld (GNU Binutils; SUSE Linux Enterprise 15) 2.39.0.20220810-150100.7.40) #1 SMP PREEMPT_DYNAMIC Mon Jul 10 18:53:13 UTC 2023 (4204a3a)

system crashes when KDE powerdevil switches the display to power saving mode on inactivity, set to 10 min in KDE preferences dialog.

I get the following in /var/log/messages

it works without crashes.

Comment 1 Takashi Iwai 2023-07-20 06:10:29 UTC

Thanks for the report.  Just to be sure, could you verify that the problem still persists with the latest kernel in OBS Kernel:SLE15-SP5 repo?
  http://download.opensuse.org/repositories/Kernel:/SLE15-SP5/pool/

Comment 2 Takashi Iwai 2023-07-20 06:45:12 UTC

In the case the latest Kernel:SLE15-SP5 still doesn't work:
I'm building another test kernel with a potential fix patch backport.  It's being built in OBS home:tiwai:bsc1213493 repo.  Once after the build finishes (takes an hour or so), could you try the package at
  http://download.opensuse.org/repositories/home:/tiwai:/bsc1213493/pool/
too?

Comment 3 Krzysztof Chmielewski 2023-07-20 09:39:34 UTC

Thanks for Your replay.

I can confirm, that the problem still persists with the latest kernel in OBS Kernel:SLE15-SP5 repo, from comment #1:

I can also confirm, that the problem is resolved in the kernel built in OBS home:tiwai:bsc1213493 repo, from comment #2:

Comment 4 Takashi Iwai 2023-07-20 10:04:45 UTC

Thanks for quick testing!

So it was the missing upstream backport of the commit 326b1e792ff08b4d8ecb9605aec98e4e5feef56e
  drm/i915/dp_mst: Add the MST topology state for modesetted CRTCs

The fix will be included in the next maintenance update on August or earlier.
Until the fix is released, please keep my patched kernel.

Comment 5 Krzysztof Chmielewski 2023-07-20 10:14:04 UTC

I will, thank You very much!
