I recreated the test on nightly where I thought I still locked with 

8fb55197e64d5988ec57b54e973daeea72c3f2ff
drm/i915: Agressive downclocking on Baytrail

reverted and I didn't lock, so it seems I messed up somewhere for that test
initially.

So reverting above alone does make me stable on both the nightly I first tested
with and drm-intel-next-queued (tested as it was over the weekend).
