Need help to resolve Kernel Panic (Log file incl.)

djdubd · #1 (**permalink**) 08-03-2009, 03:40 PM

Hello all, I am working on a 1.25 GHz PowerPC G4 w/ 1.25 GB Ram. It has an Epson 3170 Photo Scanner attached, other than that no foreign or non original hardware.

I haven't been able to be present when a Kernel Panic has actually happened, so all I have to go off of is the log, but I am pretty sure it has all the pertinent info, although it would be nice to have the first hand knowledge to relay to you.

Here are the contents of the panic.log file:

I really hope that someone here can help shine some light on the issue without me having to start randomly running through lists of suggestions that other people have made on other forums that might be detrimental to my specific situation. Appreciate any and all help that can be given.

Also to clarify just a bit farther, the panics are random as far as can be told.... There isn't a set pattern to them so it is hard to isolate to certain hardware or software.

Ok, trying to keep this up to date with what I have tried.

I have Verified and Repaired Permissions using Disk Utility
-Everything OK

Booted into Single User Mode and ran: fsck -f
-Everything OK

Booted using Command + Option + P + R

Booted using Command + Option + O + F
-ran following commands:

reset-nvram then press return
set-defaults then press return
reset-all then press return

Each said OK and then system restarted.

I am also questioning now whether the panic.log file that I posted earlier is even relevant to the issue that is occuring. My friend said that when it panics it immediately shuts off, no screen at all, and that it had done it 12 times last Thursday (07-30-09). The panic.log that I posted has a date of 07-10-09, so I don't believe it is describing this problem.

It makes me think that it is definitely hardware the way that it is crashing, something critical such as video card, memory, processor.

My friend has booted from the OS X disc and ran the full hardware tests and it passed.

The problem is intermittent and random in nature, therefore is very frustrating. PLEASE HELP!!
