I was having kernel panics quite often before 10.5.2, and they don't seem to have stopped even after the upgrade. Someone mentioned that it might have been the aftermarket RAM I installed (which is fully up to apple specs btw). But I noticed something on the error report that leads me to think it might be my M-Audio firewire external sound card instead. I've highlighted the spot in red. If anyone has some insight on this please share, Thanks!
