dmesg:

[  623.930398] [drm] GPU HANG: ecode 6:-1:0x00000000, reason: Kicking stuck
semaphore on render ring, action: continue
[  623.930493] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  623.930496] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  623.930499] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  623.930502] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
