Content of /sys/class/drm/card0/error
About a week ago, my system froze for the first time with the following syslog
entries:
Jan 31 11:22:42 TP kernel: [14282.025287] [drm] GPU HANG: ecode 9:0:0x86dffffd,

The kernel back then was: Linux 4.13.0-32-generic x86_64
This occurred several times a day. I reported this bug here:
<a href="https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746551">https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1746551</a>
I then re-installed kubuntu 17.10, plus a newer 4.15 mainline kernel, but the
crash happened again:
Linux kernel:
Linux 4.15.0-041500-generic #201802011154 SMP Thu Feb 1 11:55:45 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux
Dmesg entries:
[16127.462805] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [887], reason:
Hang on rcs0, action: reset
[16127.462806] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[16127.462807] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[16127.462807] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[16127.462807] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
