Kernel PANIC

[marlut]

I have a powerbook g4 that keeps giving me kernel panics. I have pasted what I think is the error log:

Wed Nov 26 21:51:30 2008

Can anyone help please?

It seems that the airport card is the culprit ...

Have you done anything to it recently?

No,
I have never done anything to it. I believe this airport card was installed with the computer when I purchased it. I have also been told that my 2wire599 router might be the issue, but I have gotten this error when I am working at other places, not just at home.

Any suggestions...

I really dont think a router can cause a KP, maybe the airport card is going bad.

So, should I remove or just turn off Airport to check this?
Do you have any suggestions on how to check that this is the problem?
