First kernel panic since installing OS X 10.8.2 Supplemental Update

Last week, I wrote that the OS X 10.8.2 Supplemental Update released by Apple contained a modified IOPCIFamily.kext file, which led me to speculate that the update might contain a fix for the kernel panics that have been dogging me and other users with Mac Pro computers featuring multiple NVIDIA GT 120 video cards with monitors connected to them.

This situation prompted me to undo the hack that I had been using, with relative success, to try and minimize the kernel panics on my machine.

Sadly, I have to report that, this morning, after five days of running OS X 10.8 with the 10.8.2 Supplemental Update and with the normal kext files, I had another kernel panic, with the same symptoms and the same kernel panic log information. So my conclusion is that the OS X 10.8.2 Supplemental Update did not fix the problem.

One kernel panic in five days is not so bad, but it’s still one too many for me. I have now re-implemented my hack with the IOGraphicsFamily.kext file from OS X 10.8.1, and we’ll have to see see how it goes.
