[10576.039460] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[10576.039463] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[10576.039466] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[10576.039468] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
