Hi,

Can anyone figure out what is wrong with my machine from the crash log below? Today the mac crashed and yesterday it did too, but I believe the crash log was totally different (don't remember what it was).

Thanks a lot!

Have you tried repairing permissions?

Yeah repairing permissions is one of those things that almost never fixes an issue, especially kernel panics. Kernel panics almost always indicate a hardware fault. People need to stop recommending it, it's a bit silly. Repair permissions is meant to fix broken installers, not at all meant to fix crashes.

In this case, the panic log is most definitely pointing to defective hardware. It's most likely a dying CPU, but either way, get it to an Apple Store and they'll tell you what's up. The various flags really point to a dying CPU (seriously, read the logs before you start recommending "Fix Permissions.")

(The GeForce 8800 GT's are also very unreliable so there is a chance it could be that. Apple Store will tell you.)

For reference on why repairing permissions is useless:

You really need a debug kernel to turn those Hex addresses in the stack backtrace into real kernel routines. If you aren't an ADC Select (or higher) member, though, you might not be able to get a hold of such a kernel.

That said, if I am reading that correctly, you might be having Machine Check Exception induced panics, in which case I would suspect either your memory (first) or CPU (second) going bad. :eek:

I think there's a memory tester on the installation DVD; you should run that.

That's true, it could be memory, but "Processor context corrupt" does not bode well in since that is normally not in memory.
 
A peripheral (USB or Firewire) with failing firmware can also cause panics, although it's not too common. Still, it's worth eliminating as a factor by removing any unnecessary peripherals and using a backup kb/mouse if possible.

And yeah, test that RAM.

Not too common ? The only kernel panics I have had in the last few years were caused by defective external FireWire drives.

I've never had Firewire devices cause a panic, but I have had a bad Firewire bus cause panics.

I will note again that the OP's crash log specifically points to a fault on the CPU.
 
Kernel Panic

Hello,

Have you made use of the Apple Hardware Test program to further diagnose the problem? I suggest doing that as it will tell you more information if your CPU is dying..


Another route is getting for your machine, which is Mac Pro 3,1, the Apple Service Diagnostic which luckily, I have and can provide for you.. If you are interested I can forward this useful tool to you. The Apple Hardware Test gives cryptic, hex based error codes and can be kind of difficult to diagnose problems with.

Apple Service Diagnostic is much better as it will tell you in PLAIN ENGLISH what the problem could be.. Let me know..

What is the difference between the Apple Hardware test and the Apple Service Diagnostic? Is Service Diagnostic available any ware to the end user?
