Maybe it will not take so much time after all...

* Head with FixfreqTable failed after 00:12h uptime. First with several:

[drm:__gen6_gt_force_wake_get] *ERROR* Timed out waiting for forcewake to ack
request.
[drm:__gen6_gt_wait_for_thread_c0] *ERROR* GT thread status wait timed out

Then several crashes like:

WARNING: at drivers/gpu/drm/i915/intel_pm.c:4350
gen6_gt_check_fifodbg+0x41/0x60 [i915]()

followed by an stack dump.

Report captured.

* Now testing head with FixRPControl.
