[ 1535.765260] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.

against DRI -> DRM/Intel
[ 1535.765261] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1535.765261] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
