[31825.469488] [drm] GPU HANG: ecode 0:0x85fffffd, in Xorg [1569], reason: Ring
hung, action: reset
[31825.469495] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[31825.469497] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[31825.469498] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[31825.469500] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
