--- Comment #5 from Mikael Djurfeldt <mikael at djurfeldt.com> ---
I have now tried this with the latest drm-intel kernel and the newest skl-dcm
firmware (1.26).  My libdrm is 2.4.67.

The problem still persists.

A deterministic way to provoke the hang is to run glmark2 (github.com/glmark2).

I can confirm that if I give i915.enable_rc6=0 as a kernel option, the problem
disappears.
