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.
