There's nothing in this kernel panic log messages that indicatate anything in particular. So, I'd start with the basics in troubleshooting..

Unplug ALL peripherals except Monitor, keyboard, and mouse. If you have 3rd party keyboard/mouse, go back to the Apple one. Test. Still panix?

Got 3rd party RAM? Pull it. Test. Got sound cards? SCSI cards? Any other PCI cards? Pull them. Test.

In most instances (in my experience), kernel panics are hardware related.

Duff-Man says....yellow has given you some good starting points for tracking down the problem. Bad 3rd party RAM is probably the most common problem. You also don't tell us what hardware you are running - that helps us think of potential problems/solutions.

Software can also cause problems too. Have you installed anything new lately? Give us more info about the hardware/software and we will be better able to help....oh yeah!
