[50942.980758] [drm] GPU HANG: ecode 3:0:0x0263ffc2, in Xorg [1620], reason:
Ring hung, action: reset
[50942.980771] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[50942.980777] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[50942.980783] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[50942.980789] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
