I have a friend w/ a PowerBook G4 (15", 1.5 GHz, no multi-touch trackpad) that's getting lots of kernel panics. The Genius Bar diagnosed it as a bad HDD, so I swapped the HDD for them. It didn't solve the problem. I've been trying to grok the panic log files, but it makes no sense to me. I'm hoping that someone here can help me out. The log files are here: http://dimwell.net/temp/panic_logs/ In my experience, most kernel panics are due to bad hardware or bad drivers. I don't have the machine in my possession, so I can't do a lot of troubleshooting right away. I copied these log files, hoping I'd be able to figure something out from there. Any help or other guidance would be hugely appreciated. Thanks. EDIT: I'll be picking up the machine on Tuesday, then running a full scan of TechTool (via an AppleCare disc) on it. I don't have any spare RAM to swap in or out, but I'll try to systematically eliminate that as a culprit, as well.
