Georges, what peripherals do you have attached? Any external hard drives?
Can you duplicate the kernel panic, or was it a one-off? If it doesn't happen again, then I wouldn't worry about it.
Try Googling ""IOSCSIPeripheralDeviceType00" + kernel panic" (with the quotes around the IOSCSI bit) - you'll see a a number of references where this bit pops up, and it always seems to have to do with peripheral hard drives.
Which computer, OS and what, if any, external devices do you have? It helps if you tell us this from the outset, as you have several Macs with different OS' listed in your profile and sometimes these issues are particular to hardware or operating systems.
