[43503.816050] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[43503.816052] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[43503.816054] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[43503.816056] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
