[ 35.849634] [drm] GPU HANG: ecode 8:1:0x21204b77, in X [437], reason: Hang
on bcs0, action: reset
[ 35.849639] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 35.849640] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 35.849642] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 35.849643] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
