Please help me diagnose this kernel panic, thank you

Question

this kernel panic (I have it sporadically) seems to be related to airport somehow.
( com.apple.driver.AirPortBrcm43xx(305.25.82)@0x330a3000->0x331cffff)?
is there any way for me to replace or upgrade my airport driver, or prevent this from occurring?
thank you very much for any and all assistance, no matter how small!

Answer 1

This seems odd and makes me think it might be a memory issue (page faults are memory related):
That should point to where the problem occurred, but points to 0x0. Micron is good RAM, but there’s always the possibility one stick is bad.
However, you have several known trouble-makers and a few kexts that I don’t know about.
Logmein
Little Snitch
Nvidia CUDA
ContourDesign Shuttle
If Parallels is up to date, it shouldn’t be a problem.
Carolyn has already suggested the ones I would find suspect and disable to test. You can just boot into Safe Mode to isolate problem kexts. Booting in Safe Mode should disable them. If you don’t get any Panics, then it would point to one of the kexts.
OS X: What is Safe Boot, Safe Mode?
