After Wayland taking too long to trigger, exited and entered Xorg.
Didn't take long before I hit

workqueue: PF_MEMALLOC task 41(khugepaged) is flushing !WQ_MEM_RECLAIM
i915-userptr-release: (NULL)

I suppose if I continue this session, it will repeat last nights events
and finally RCS0 hang and reset the GPU. This looks like a pattern to me.
