Hey everyone thought I would post a quick note to let everyone know if you are getting Kernel Panics DO NOT RE-FORMAT your machine! the very first thing you should do is check your ram. I bought a new stick of generic 512mb ram this past Friday ran home and stuck in my Powermac G4 DP 1.25Ghz and bam! the Kernel panics started to fly! I ran a memory test and the test would not even run on the stick. I took the new stick out and have been in heaven ever since, not one Kernel panic or restart. Long story short yes brand new memory can be bad right out of the package no matter where it comes from.
