[  667.365989] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.

against DRI -> DRM/Intel
[  667.365990] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  667.365991] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
