I have an iBook G3 900 running 10.3.3 and 640MB memory. I bought it new in Feb and it has hardly been used. I keep getting kernel panics. They have been going at least one a day for 2 weeks now. I removed the memory and Airport but it hasn't fixed the problem. I even did a clean install of Panther without any luck. The Hardware Test CD give it a clean bill of health. I don't have anything attached through USB or or Firewire. I have all updates installed. I've tried everything I know short of calling Apple. Here is the latest log. Does anyone have any idea what this means? Any help would be appreciated.

Well, I've had 4 more panics since I originally posted. I rebooted after the last one and it totally crashed. It powered itself off and won't turn back on. No chime, no nothing. I guess it's time to call Apple. Any ideas what is going on with this thing? Logic board maybe?

I have taken the memory out and still get the panics. This thing is driving me nuts. I'm just glad it isn't my primary system.

I have been able to reboot the system by taking the battery out and letting the system set for about 10 minutes. It will reboot fine after that.

I called Applecare and went through all the usual questions and disk repairs. The person I talked to wants me to use the Apple Hardware test CD in a loop cycle over night. I didn't know that this could be done but it's kinda cool. Boot up with the CD and press CTRL + L. The test will run in a loop cycle until their is an error or I stop it. Whatever comes of it I will call back tomorrow.
