I've just got a Kernel Panic. I'm trying to find the source of the problem. I thought it could be the RAM memory but not pretty sure though. This is the report of the kernel but I'm not able to spot the problem in it:

This part seems interesting:

Could it be a problem with Airport ?

I think I found the source of the problem: the kernel panic only happens if the computer is NOT connected to the power supply. Does this mean that the problem is the Battery? Please help. –  chefnelone Aug 24 '12 at 6:55
The place in the code where it panics can be worked out from the backtrace. It looks like it's somewhere in the kernel itself, not a kext. You'd have to look up the addresses in the trace (0x21b837 etc.) in the symbol table for your specific kernel, using the kernel debug kit for that version of OSX. Note that this may or may not tell you the cause, which can be a lot of things, not necessarily the code where the crash is occurring. What user action triggers the kernel panic? –  pmjordan Sep 15 '12 at 14:47
