  [  191.914529] [drm] GPU HANG: ecode 5:1:0x01000000, reason: Ring hung, action: reset
  [  191.914533] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
  [  191.914535] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
  [  191.914536] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
  [  191.914538] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
