"GPU hung" there is the key bit.  It means your GPU has hung.  For this
kind of bug, the data you need to be collecting is your 'dmesg' and this
file:

  /sys/kernel/debug/dri/0/i915_error_state

Also, since these types of issues can be hard to troubleshoot, steps to
reproduce the problem are very important.  Most of the time they seem
random, but there's usually activities that tend to trigger them more
often and finding out what those activities are can help pinpoint what
section of code is at fault.
