Content of /sys/class/drm/card0/error

System is barely usable. I am losing part, or all, of my GUI all the time.
A crash as below will eat all keyboard inputs and only allow ctrl-alt-f1 and
the like.


As per dmesg:

[ 2207.681554] [drm] stuck on render ring
[ 2207.681558] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 2207.681558] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2207.681559] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2207.681560] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2207.681560] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
