(drv_hangman:6411) DEBUG: dfs entry i915_error_state read 'no error 
state collected'

So hangman wasn't able to hang the ring?

[  406.005039] [drm:i915_hangcheck_elapsed [i915]] *ERROR* Hangcheck 
timer elapsed... render ring idle

This looks like a real regression (but unrelated to this patch, hsw 
doesn't use execlists). I opened 
https://bugs.freedesktop.org/show_bug.cgi?id=94289
Unfortunately I don't have a hsw to do a bisect.

The usual
[  196.712245] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* 
CPU pipe A FIFO underrun

Again, unrelated to this patch, snd and ilk don't have execlists.

Looks like it has been like this for a while: 
/archive/results/CI_IGT_test/igt@kms_force_connector_basic@force-load-detect.html

Also, this subtest is quite recent, 
https://cgit.freedesktop.org/xorg/app/intel-gpu-tools/commit/?id=7670e286f5043d04af0cd1e6df1f092b5bcaf09e

Again,
[  682.562490] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* 
CPU pipe A FIFO underrun

Same as: https://bugs.freedesktop.org/show_bug.cgi?id=93294 (cpu_hotplug 
lockdep fail).
