Hi,

I just found this in dmesg:
[ 8916.544423] [drm:ring_stuck] *ERROR* Kicking stuck semaphore on render ring
[ 8916.544428] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 8916.544429] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 8916.544430] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 8916.544430] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 8916.544440] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I was playing a video at that time.
