(In reply to comment #183)
I recommend configuring i915.semaphores=0. I did it and it doesn't
freeze anymore.

Bug description:
I'm getting errors about GPU hangs every minute or so (usually only
when using FF and scrolling a webpage or something). I also get an
annoying ubuntu dialog saying there is a "system error".
This didn't happen with 3.5.0-24-generic.
Here is the dmesg:
