As the message suggests..

"You have some hardware problem, likely on the PCI bus."

This doesn't sound like a software problem.  Random NMIs are usually a bad sign.

Comment 2 Tom London 2007-07-07 15:20:06 UTC

I got these frequently with the 'broken' e1000 drivers of a few months ago, and
not before nor since except this one.....

I filed this just in case there was some similar issue.

I'll close if you like....

Haven't seen a repeat.

Closing.
