I had two system crashes this week, my first time dealing with kernel panic too. Both times I was using the 9600 from my MBP. Apparently from what I noticed it was too hot. I did some research on the 'net and apparently Firefox could be the culprit, but I have my doubts a simple browser could crash a linux system, maybe I'm just too naïve? I noticed it was quite hot, even if I weren't doing anything intensive, so maybe I should just pump the fans to 6000rpm to keep the 9600 sane? Has anyone had a system crash while running the fans that fast and (theoretically) keeping the 9600 cool?
