gpu error file on 4.13.5-200.fc26.x86_64
This problem reappeared on 4.13.5-200.fc26.x86_64 last Friday.
[774249.632109] [drm] GPU HANG: ecode 6:0:0x85fffff8, in Xorg [696], reason:
Hang on rcs0, action: reset
[774249.632110] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[774249.632111] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[774249.632111] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[774249.632111] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[774249.632112] [drm] GPU crash dump saved to /sys/class/drm/card0/error
