Xorg crashes with SIGABRT

[Michael Schanne]

I am running an Intel Kabylake CPU with Ubuntu 22.04, and i915 graphics driver. I am seeing random Xorg crashes due to SIGABRT, which kicks me back to the login screen.

Ubuntu version: 22.04
Kernel version: 5.19.0-50-generic
libgl1-mesa-dri version: 23.0.4-0ubuntu1~22.04.1

I am seeing this message in kern.log:

i915 0000:00:02.0: [drm] GPU HANG: ecode 9:1:85dffffb, in Xorg [1617]

I have also gotten a core dump; here is the track trace:

This post describes a similar issue:
https://gitlab.freedesktop.org/drm/intel/-/issues/4858

I tried using a workaround from the above link, to set GPU to max frequency using command "intel_gpu_frequency -m", this seemed to reduce the rate of occurrence from once per day to once every 3 days, but this is not a permanent solution.

Tried kernel parameter i915.enable_dc=0 as suggested by https://wiki.archlinux.org/title/intel_graphics#Crash.2Ffreeze_on_low_power_Intel_CPUs; still crashes
