Kernel log:

[21706.557061] [drm] GPU HANG: ecode 0:0x85ffbcff, in Prison Architec [10485],
reason: Ring hung, action: reset
[21706.557063] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[21706.557064] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[21706.557065] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[21706.557066] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
