Two items which are missed (sort of implied though): motherboard BIOS
version, and SCSI card BIOS version.
Let's try to make an effort to get some hardware and software stats from
other folks so we can determine what the commonality in all of this is.
I can keep track of this stuff if need be.
We know for sure at this point that some of the reported systems
experiencing this problem work fine on Linux (all memory seen, and no
data corruption), so that "sort of" clears the hardware of being bad or
