I've found it!

Strightforward git bisect tells that e6b0b6a82f9c93fe3dd060ae54719456474a74a3
is the first bad commit. But it's merge commit which merges v3.5-rc7 into
drm-next. None of it's parents has this problem. So, I've rebased all these
patches from drm-next to v3.5-rc7 and bisected among them.

And the winner is b4ae3f22d238617ca11610b29fde16cf8c0bc6e0 (drm/i915: load boot
context at driver init time) which refers to
https://bugs.freedesktop.org/show_bug.cgi?id=50237 Seems like there is no
public documentation about this stuff so I have no idea what the hell is
happening here.

I've reverted that commit from 3.9.9 and it works like a charm. After that my
automatic script unable to reproduce this problem.
