I just realised I have a similar motherboard (Supermicro H8DAE-2 ) with
the same chipset and also a pair of quadcore opterons on it.
Check these 2 options in the AMI Bios :
Advanced Chipset Control > Northbridge
Set IOMMU MODE to 1 GB
(unless you have an agp videocard in this system, then it should be set
to "AGP present" )
Processor & Clock Options
Set Secure Virtual Machine Mode to Enabled
Without those settings in my experience linux 64-bit kernel is very
unreliable on this system.
With those settings it's been running rock steady for 7 years now.
(it's my main workstation pc ).
