[27643.613948] [drm] GPU HANG: ecode 9:0:0x283b3249, in X [2799], reason: hang
on rcs0, action: reset
[27643.613949] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[27643.613950] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[27643.613950] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[27643.613951] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

if available in BIOS.
