I need help with some recent Kernal Panics I have been having. My specs are:

Mac g4 PPC quicksilver tower (2002 model)

Dual 1.6 Ghz, 1.5 GB SDRAM

Mac 10.4.11

Yea its an old computer but it has run great for me all these years, I have never had a kernel panic before and now only a couple days ago I have been having nothing BUT Kernel panics. Here is the data from my panic.log file:

Code:

I have upgraded the hardware on this machine (new ram, processor, usb 2.0 card) and I have read that hardware problems do cause Kernel Panics, but it has been almost a year and half since I have upgraded and it has run fine.

I did update Itunes recently to version 9 and so far I have linked all the panics back to it, whenever I have one Itunes is always running. I could be wrong though, any help is greatly appreciated.
 
Well the line "crash info for cpu 1" should give you the clue it might be time to backup and replace the Mac.
 
Is that the entire log entry? Sure looks like a deceptively short backtrace log... which makes me lean toward something hardware-related, but I'm not sure.

If there's more detail included in the log, like a software backtrace, please post...
