Yeah, We've got a mix of 2650 and 2850s, and our 2850s have been rock
solid stable, unlike the 2650s.  I was actually kinda surprised to see
how many people have problems with the 2850s.

Apparently, the 2850 mobos have a built in RAID that's pretty stable
(it's got a PERC number I can't remembeR), but ordering them with an add
on Perc RAID controller appears to make them somewhat unstable as well.

On recommendation I've seen repeatedly is to use the --noapic option at
boot time.

Just FYI
