I have had a private email from someone who has experienced similar
lock-ups with twin Opteron systems and PCI cards, so from that point of

I have some quad Opterons running too, and they seem fine, although they
are pure compute servers with just a local IDE drive. (and they are
running SuSE 64-bit which is what the application demands)

Interesting - the private mail was from me, and I've got two dual Opterons in service. The one with significantly more PCI activity has significantly more problems then the one with less PCI activity.


There appears to be a trend here then, if 3 is a trend.

We're moving to a single PCI card (8-port 3ware, iirc) for all off-motherboard disk access, and I'll report back if that changes anything.
