[ 7360.049796] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 7360.049801] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 7360.049805] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 7360.049809] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
