--- Comment #2 from Jesse Barnes <jbarnes at virtuousgeek.org> ---
Can you attach your dmesg as well?  Sounds like a config problem, like maybe
you don't have the i915 kernel driver loaded or something.  Please boot with
drm.debug=0xf on the kernel command line and attach the dmesg from a fresh boot
when this issue happens.
