Ring hung, action: reset
[28782.564979] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[28782.564980] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[28782.564981] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[28782.564981] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
