I have been doing a little more investigation under the guidance of,
and with the help of, master kernel builder, Sir Engelhardt. (I hope I
remembered that right ;-)

Nope, I'm sure he's German so he can't be a Sir - maybe a Herr? - sounds
very similar :-)

One issue that looks promising as the culprit is the nvidia module.
Were you by chance also loading the nvidia module on your Gigabyte
system? What video card were you using?

No, I've got an ATI Radeon card and I'm using the AMD drivers.

Also, what is a good torture test to run to see if I can make the
system lock. IIRC you were using mprime. Any other simple ones you know
of? Thanks.

mprime is the best stress test I know. It just seems to be able to get
into all the corners where you'd normally never go.


Well we have plenty of mcelog errors before removing the nvidia driver and using the stock "nv" driver, we have not seen any since. That's running mprime while running XP with it downloading and installing updates as well. The combination of removing the nvidia driver and passing "acpi_use_timer_override" seems to have taken care of 99% of the problem. However the mce errors are hardware errors, so it looks like the nvidia 8600GT card causes real problems when the full proprietary nvidia kernel module is loaded. Hmm, no more compiz until this is resolved.

Thanks for your response
