Yes, that seems to be it for me also - but just to confuse things I've
been running with that for several weeks without incident, so something
brought in from the recent merges/a new patch doesn't play nicely with it.

If you wanted to test you could get back to how drm-next-3.19-wip was 
last week by

git reset --hard 3.18.0-rc2-gc76c717

and you can see it's there with git log about 6/7 commits down.
