This is a fglrx bug, kas_spin_lock and KAS_GetExecutionLevel are totally not preempt safe. Unfortunately this is most likely hurting your GPU performance and you would be better off using the -generic kernel. I see you are on a laptop as well, and the preempt kernel very negatively impacts your battery life if that is an issue so that's could be another reason to use the standard kernel.

affects:	linux (Ubuntu) → fglrx-installer (Ubuntu)
Changed in fglrx-installer (Ubuntu):
importance:	Undecided → Medium
status:	New → Confirmed

Guess I'll be switching to -generic until this is resolved.. battery aside, I prefer preempt for desktop responsiveness.
