Description Nicolas PEYRESAUBES 2020-01-21 23:00:00 CET

Description of problem:

From time to time on Dell Latitude 5400 or Dell Optiplex 7050 with Plasma and "default" desktop kernelI get some GPU hang message in /var/log/syslog, and most of the time it leads to a completely frozen desktop / system

Jan 21 08:52:04 rivendell kernel: [80848.556476] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Jan 21 08:52:04 rivendell kernel: [80848.556478] drm/i915 developers can then reassign to the right component if it's not a kernel issue.

This behaviour doesn't seem to happen with "Linus" Kernels (5.1.14-1.mga7 for example), and doesnt' occur on Latitude E6330. Had no trouble with Mageia 6.
I've been testing Latitude 5400 and Optiplex 7050 with debian buster (older kernel) without any issue

How reproducible:


Steps to Reproduce:
1. random freeze which occured 3 times in 4 hours

The bug seems to be linked to a kernel or more specifically to the intel driver

Couldn't it be related to https://bugs.freedesktop.org/show_bug.cgi?id=111805 ???

Can you say what processor & graphics hardware you have this problem on? (unless 'drm/i915' says it all).
Also, since when (kernel version) you have had the problem. If you know the video driver, see if that has been updated recently:
 $ rpm -qa --last | grep <driver package name>
will show its most recent date.

That other bug does indeed look relevant; thanks for the pointer.
 https://bugs.freedesktop.org/show_bug.cgi?id=111805#c27 :
"Hi. I'm hitting the same problem now with 5.4.0-rc4+ series
I just had 38 days perfectly stable uptime on 5.3.0, before upgrading to 5.4.0-rc series for improvements in S0ix suspend residency.
Unfortunately some kind of a serious graphics regression has happened here."

There have been several problems reported after the move to kernel 5.4. If you can, for the moment, boot into a 5.3 one - or an earlier 5.4 one that did not give you trouble.

Assigning to kernel/drivers. They might ask for more info, like dmesg (to add as a bug attachment).
