HI guys,
I finally got some type of crash dump from my system. I have tried Ubuntu variations of the 2.6.35, 2.6.36, and 2.6.37 kernels, all of which have crashed on me.
Finally, 2.6.37 gave me a trace on the console screen. I had to copy it down by hand, so don't take it too literally.
Here is the data. I intentionally left out all of the hex addresses in the call trace. It seems pretty obvious to me that something is amiss in the hardware. I wonder if my heat syncs are full of dust. That will be the first thing I check.
Any helpful advice would be most appreciated.
Thanks!
Andy

Well, that about says it: a CRC error on the HyperTransport link. That sure sounds like a hardware glitch. You can certainly try cleaning out the heat sinks and fans, but if that doesn't work, it may be time for a new CPU and/or mobo.
