[22168.029016] [drm] GPU HANG: ecode 9:0:0x84dffff8, in Xorg [2693], reason:
Engine(s) hung, action: reset
[22168.029022] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[22168.029025] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[22168.029029] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[22168.029033] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
