Can anyone help me decipher this kernel panic? It seems to be pointing to a faulty CPU - but the Apple Store tried replacing the processor tray and the computer wasn't behaving normally. They didn't have the logicboard or backplane board available to test. I'm wondering if having the backplane board replaced could be a potential solution. Just wanted to get some opinions before I spent the money/time to try and fix the problem.

For Apple store repairing. They should not charge you until they can pin point the issue. Running those tests should be free of charge.

It's hard to tell if that's really CPU related.

1) The "CPU...." in the KP usually has nothing to do with CPU failure
2) Both logic board and CPU tray can make the CPU unable to perform

If they has the CPU tray for swap test. Just ask them to do it, and request them to order to logic board now just in case need that to test later (this is also free of charge).

If there is no more KP after CPU tray swap. Then I will happy to take that as the diagnostic result.

They should give you 3 months of warranty if anything goes wrong. That should be good enough. If you experience KP again. Then you can request a logic board replacement (for free by that time, and the parts should be available).
 
The MacPro 4,1 model is no longer being supported by Apple - they can't order the logic board or back plane, I have to go to a third party repair. They can do parts/labor for $400, but that's no guarantee that the problem will be fixed. If the problem persists with a new logic board, I'm out the labor to replace the logic board. That's what I'm trying to weigh.

In this case, I will spend $400 to buy a whole used good condition 4,1.
 
That's a 2008 Mac Pro. The hardware is completely different.

Yeah, didn't really see that until I posted it. Looks like $600 from Mac of All Trades if I want to pickup a direct replacement.

Been reading a ton of stuff on all of the upgrades you can do to this machine and have it feel relatively modern. Wondering if I just sink that kind of cash or not.
