Unlikely i'd say. I have 1000+ successful overnight tests on the latest 
tree Linus pushed out:

 3ef884b: Merge branch 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/d

So that's a guaranteed 'good' kernel.

The moment i merged 053fe57 into -tip the lockups started, so that's a 
guaranteed 'bad' kernel. There's only the TTY changes between those two 
points that look remotely related.

It's spurious though so quite hard to bisect. I tried one bisection 
today already and it got on the wrong track. I'll do a brute-force 
revert of the commits i quoted, lets see what happens.
