The trusty PowerMac G4 DP 800 has been crashing a lot lately.
Not sure what's going on, but here are the Panic logs... Any thoughts?

[Scottapotmas]

im not absolutely certain, but its to do with a crash in the airport kexts or plists...

Kernel loadable modules in backtrace (with dependencies):
com.apple.iokit.AppleAirPort2(405.1)@0x82a000
dependency: com.apple.iokit.IONetworkingFamily(1.5.0)@0x5a3000
dependency: com.apple.iokit.IOPCIFamily(1.7)@0x491000

is a givaway, com.apple.iokit..AppleAirPort2 is the problem and the following means that IONetworking family and IOPCIFamily require or call to it...

So the Airport2 driver is missing something or something and then the networking and PCI stuff won't work...


I guess you could try backing it up and removing it, or updating... but its PPC, so im not quite sure if there would be a newer one... I guess i diagnosed, but don't know how to help

Thanks Scott, I thought that was the problem. Maybe it's corrupted.

Already had Airport turned off. Guess I have to reinstall / re-update.
