cat /sys/class/drm/card0/error > sys-class-drm-card0-error

It is probably the same/similar to one of the other 4 with such a error message:


but it is not obvious which one should be - all of them have some follow-ups and non-trivial responses.

[177570.522360] i915 0000:00:02.0: GPU HANG: ecode 9:0:0x00000000, hang on rcs0
[177570.522364] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[177570.522365] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[177570.522366] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[177570.522367] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

[177570.523407] i915 0000:00:02.0: Resetting rcs0 for hang on rcs0

It happened almost 4 days ago - but evidently recovered, as I did not notice until I look at dmesg - the system is still up and functional after 4 days after that event.

I am filing here, mostly because the message said I should. Please feel free to resolve the duplicate of one of the others, etc.
