[ 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 https://distrowatch.com/search.php
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.

I hope this information helps.
