[ 219.708014] drm/i915: Resetting chip after gpu hang
[ 221.706203] [drm] RC6 on
I occasionally encounter freezing while using various applications in x11. I am
able to reproduce the freeze 100 percent of the time while using Firefox and
visiting <a href="https://distrowatch.com/search.php">https://distrowatch.com/search.php</a>
After scrolling through the page the gpu will hang in about 1-2 seconds of
scrolling. This is not the only instance of the gpu freezing, however it is the
only instance I can reproduce on demand.

Intel(R) Core(TM) i3-6100U CPU @ 2.30GHz GenuineIntel GNU/Linux)
I hope this information helps.</pre>
