Question Crashing "BUG: soft lockup - CPU#1 stuck for 11s"

I was running Ubuntu 8.04.2 and it started crashing after 12H or more of operation. So I switched to Debian 5.0.1 only to find the same errors.

Currently running Debian 5.0.1 amd64 with the default kernel

kern.log shows numerous errors like the one below.
After the a crash the first line of the error will repeat the same CPU# and what I assume is the process and pid.

Each crash the CPU and process listed may be different.

I've updated the bios the latest and updated all my packeges.

Currently I'm running memtest to see if its a memory issues. Any help would be wonderful.

Attached is a more detailed listing of the errors

At work we had an xSeries 460 throwing the same sort of errors: turned out to be a bad CPU. May or may not be the same issue, but ours was fixed upon removing that CPU.

Sigh. No joy. Memtest gave no errors.

Remove one CPU and still goe the "cpu stuck" message. swapped cpu's now the system just hangs a little after the grub screen.

And the latest Debian and Ubuntu installers both crash immediately and the error messages scroll too fast to be of any use.

I have a feeling its the motherboard, it's been RMA's 3 times and cost me nearly $200 in shipping. It's an obsolete AMD FX system so I'm going to give up on it for now. Unless i can fine a replacement MOBO for super cheap.

Sigh, 1200$ in parts wasting away, for now.
