Anyone understand this panic log?

[Ahiqar]

I have the last white iMac, the Core 2 Duo from late 2006, 17 inch screen, and I am having what I think is a kernel panic. (The machine forces me to restart.) I am wondering if anyone might be able to ID the source of the problem by reading the panic log. The log reads:

Mon Sep 22 19:53:13 2008

Thanks a lot!

Oh, forgot to add that I am running 10.4.11

Well it appears to me that whatever you were running was trying to use the AirPort network but was receiving invalid data and had no way to recover.

Thanks

for the response. So does that mean that I have an airport card problem? a network problem? Can I even determine what the problem is? This happens each time I turn on the machine. Sometimes it takes 5 minutes. Sometimes it happens in 45 seconds.

I would suggest taking it into an Apple Store or Repair Center and have them re-seat the Airport Card and the memory (just to be on the safe side). Or take them the log and see if they can decipher it more. Have you tried turning off AirPort and then does the KP occur?

com.apple.driver.AirPortBrcm43xx - This is the Driver for the Airport Card
IO80211Family - This is the IEEE number for Wi-Fi.

The first thing I would do is unplug the card if you can, and see if the problem persists. Hopefully it doesn't, because you obviously can't uninstall anything if you can't get started.

If that allows you to start, I would try getting the drivers for the card totally out, and then reinstall them clean (hopefully you have a disc - if not, you should be able to get them from the site.) Reinstall fresh driver files, shut down the computer, and plug the card back in. If you still have a problem, the card is probably bad.

Thanks

for both replies. I will try to shut down airport and the network and see if that helps. If not, I will probably just take it to the Apple Store and show them the log. (I don't feel very confident doing any repair myself.) It's under Apple Care still. I'll suggest they check the card.

Thanks a lot!
