>From time to time I get some GPU hangs which seems to occur rather randomly,
sometimes I am just at the terminal, others browsing, I notice because the
desktop freezes during some seconds, but I still can hear audio going on, later
the desktop continues working as before.
I am attaching the syslog and the GPU crash dump.
[ 2850.274841] [drm:ring_stuck] *ERROR* Kicking stuck semaphore on render ring
[ 2850.274852] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 2850.274853] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2850.274855] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2850.274856] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2850.274857] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.</pre>
