Removing linux-firmware would disable some features of the i915 module (depending on the particular GPU). Using optimus would also avoid using some features of the i915 module.
Please see [1] for how to file a bug in the i915 module.

Is this still happening? Any luck reporting it upstream? Tried a newer kernel?
