Kernel Panic & Hardware Test Error : 4SNS/1/40000000:TCOD

I got the TCOD error code from the Hardware Test I performed on the Installation Disc 1 that came with the MBP. I am very sure it says TCOD and just ran the test again to reconfirm.

A sample of my panic log reads:

Oh, the 2GB RAM on the MBP came from Apple. So I hope if they were to blame the RAM, they'd replace it too. 🙂

But I do hope the kernel panics go away after the second logic board replacement. It's so strange to get a "bad" logic board after another. If the kernel panics persist, I don't know how many more logic board changes I can endure.... the downtime, the backing up and repetitive travel (as anyone who's had multiple visits to the Applecare centers can attest to), can be very tiring.

Thanks for the replies so far, I really appreciate your generosity in sharing knowledge and thoughts.

I am assuming my logic board has multiple problems.

Thanks for the link. It's interesting.

I do use Azureus. Have stopped using it for a while. But the kernel panics has happened even while just watching Quicktime trailers. In any case, the TCOD hardware test error still won't go away and continues to linger as a possible indication of something bigger?

I will eliminate that with a logic board replacement first.

But not that it's completely related - I sincerely hope if the problem really is Azureus maxing out the Wi-Fi connection causing kernel panics... that the worst case scenario doesn't happen :

"Apple might still not acknowledge the problem as their responsibility and Azureus continues to think neither is it theirs to fix (because they can't or won't), then the consumers will be the biggest losers."

Oh dear. Sounds like you've got even more serious issues with your MBP. It must be really frustrating to have it KP on you while editing photos. I for one noticed something equally frustrating- a problem which has been talked about a lot in the forums... "the first letter missing syndrome". And it is worse for me, as I am a writer.

I am bringing mine in for a logic board replacement soon. Hopefully that should fix the kernel panic problem.

Will keep you posted.

Ok, it's official. My kernel panics may not be related to Azureus.

My Black Macbook has NO Azureus and it just panicked for the second time. It's newly clean installed with Leopard and I have only installed VLC on it. The Macbook has never KP-ed before in 10.4.10 or 10.4.9. This is a disappointing fact. I may not like everything else about Windows Vista, but it has never hung on me (yet).

I'd like to boast reliability on the Mac OS but problems with both relatively latest C2D Black Macbook and C2D 17-inch Macbook Pro is leaving me with a bitter Apple.

What do I have to do to be able to use my Apple computer for work reliably, seriously? Lug around a 8-core Mac Pro? Something is really wrong with the Apple's hardware drivers (especially Airport Atheros) or Leopard's codes... ADMIT IT APPLE, AND FIX IT.
