[  378.776909] i915 0000:00:02.0: GPU HANG: ecode 9:1:0xfffffffe, in  [0], hang
on rcs0
[  378.776915] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  378.776917] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  378.776919] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  378.776921] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[  378.776923] [drm] GPU crash dump saved to /sys/class/drm/card0/error
