How do you check this ? :)
I wonder if I have the same problem on my mainboard.
Everything is ok under moderate load, but on high load it breaks down
(the system locks up, which makes me suspect some low level issue, like
incorrectly setup PCI bridges ?).

Ah, you have multiple PCI busses and a PCI-PCI bridge, which I don't, so
its not like my problem probably (hm).
