I tried again a bisect on a different branch = drm-intel-next-queued

I managed to arrange not to hit any merges and the bisect did call 

8fb55197e64d5988ec57b54e973daeea72c3f2ff
drm/i915: Agressive downclocking on Baytrail

In fact while sitting on that commit for the first time ever I locked without
the use of kodi. Just fast scrolling in a maximised  xterm from a make
modules_install.

Generally the locks were much quicker than I am used to - 5-10 mins with kodi.

Just to confuse things, on the older nightly, as I said above, I still locked
with this reverted - on the new branch (which has more new commits since I
tested the nightly) I so far haven't locked with it reverted.
