Oct 27 13:06:14 SNB-1 kernel: [  166.813634] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Oct 27 13:06:14 SNB-1 kernel: [  166.813635] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
Oct 27 13:06:14 SNB-1 kernel: [  166.813636] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Oct 27 13:06:14 SNB-1 kernel: [  166.813636] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
