This started to appear in logs:

Can you check the drm-intel-fixes branch at
git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/drm-intel.git?
It has a fix for laod detection that might help.

I noticed very similar problems when I upgraded from 3.2 to 3.3-rc4 on
my laptop. Same error message but the symptoms were worse, got a black
screen when the display manager started X.

3.3-rc4 plus these two patches from drm-intel-fixes works great.
4e9bb47bd29e02f2daaa7bdb2a8ddf977bf76f06 [PATCH 2/2] drm/i915: fix a
sprite watermark computation to avoid divide by zero if xpos<0
5ca0c34ae28344b6b4ca3036bc82f89c8db16a59 [PATCH 1/2] drm/i915: fix mode
set on load pipe. (v2)
Thanks!
