Public bug reported:
There might be two causes of this bug:
- I had S-ATA ALPM activated and high IO activity (unTarring a system backup)
- My screen started flickering upon opening Google MapsGL, but the GPU seemed
to be hanging before that.
I added i915.i915_enable_rc6=0 to my cmdline now, and it seems to be
working fine (but rc6 was the whole reason for upgrading to precise)
