Hi,

I like to be as accurate as possible, since this occurred, I've removed 
threadirqs..

Please disregard this, I also updated the BIOS on the same day (BIOS 
update + kernel update), I'm re-running w/thread irqs enabled again, and 
I'll update you if there are any issues, thanks.

(I've set the bios to factory defaults -> tweaked), we'll see what 
happens.

Justin.
