Uhh "C" drive?

Kernel panics can be caused by:

Bad memory
Hardware faults
Software faults.

OR combinations of all of the above :-/

First boot in safe mode. if it KP's then you can eliminate third-party  
drivers as a cause. If not, proceed to the next step.

If you're still getting kernel panics after removing the fw devices,  
start by removing ALL additional devices.

If the KP's stop, then add things back one at a time until they start  
re-appearing. The last thing added is the cause. Check to see that  
there isn't an updated driver or something.

If the KP's continue even after stripping it down to bare stock AND in  
safe mode, run Applejack+Memtest to check the memory. If the memory  
passes, (and the system doesn't barf during the Applejack and memtest  
process) try an Archive&Install of the system software to elimiinate a  
corrupted system.

(if it barfs during Applejack; during wish you will not get a Kernel  
panic but a message about a segfault or segmentation fault, try the  
A&I as well)

If it *STILL* KP's after that, you have a hardware fault.
