Hey all, I have a 2006 2.16 C2D iMac running 10.7.5, and I experienced a kernel panic late last night. I was listening to music, browsing the net, and had a few programs open. I was suddenly assaulted with the kernel panic screen, and after a few seconds the Mac shut off. I waited a few seconds, and then turned the Mac back on. I ran into the grey prohibitory sign, so I rebooted the Mac and attempted to use Safe Mode, but the Mac shut down while I held the Shift key. I restarted again, this time selecting the Recovery HD partition, which successfully started up. I ran Disk Utility, which reported no errors, but I wasn't convinced. I also ran fsck -f in Terminal, but it didn't report anything strange either. I shut down the Mac again and this time booted from a DiskWarrior USB stick I had created for just such emergencies. It scanned the drive, and found a few damaged files, which I repaired by rebuilding the file directory. I rebooted again as usual, crossed my fingers, and lo and behold I am back in business! I didn't waste any time after that. After ensuring I had my Time Machine backed up with the latest changes to my system, I ran TechTool Pro on my Mac, and found that the Hardware ECC Recovered range looked questionable, but I'm not sure if i should worry about it. I did find the kernel panic log, and I wanted to know if someone here would be gracious enough to examine it and let me know what sort of problem my Mac ran into. Based on the TechTool Pro report, I suspect the hard drive, but that might not be it. I've attached a copy of the readout from the kernel panic log in the Console.app. I've also enclosed a snapshot of the TechTool Pro test result of the hard drive in the Mac.
