Mac G4 kernel trap CPU 0 Kernel Panic?
Looks like a normal Kernal Panic. How long has it been since you ran Repair Permissions? Sometimes that helps. I have one G4 that has been having Kernal Panics since it was new (2001) and it's still going strong.


Run Repair Permissions about once a month and every time you do a system update. You find this under Applications/Utilities/Disk Utility/Repair Permissions. I keep an alias of the app on my dock so I don't have to look it up when I run it.


If they kernal panics are too frequent see if you have added anything new recently, like RAM, PCI cards, etc. If you haven't and they bother you call Apple for advice.
