I am just a user - but after some testing maybe it would be better if
you can reproduce on similar kernel to your old one and bisect that.

On drm-next-3.19-wip I only have to go back 4 commits to hit ones I've
been running for weeks (and I am still failing if I reset to there) so
for me at least bisecting this tree isn't really an option - I wouldn't
be testing like for like.

Stable for me is drm-next-3.19-wip at 3.18.0-rc2-gc76c717 failing
current = 3.18.0-rc4-gbe762d1 so it seems to be something in the merge
that took rc-2 to rc-4.
