Hi,

Below some more info on my two systems:

The promise card is sharing IRQ11 with usb, the other libata device, and 
nForce2 (wonder what that is?)

I second that (although I'm really clueless about PCI).

Could it be that at 3.0Gbps with 4 ports running at full speed 
contention on the pci bus cause this behavior? This would explain why a 
PCI-X port helps (or limiting to 1.5Gbps). Or maybe it is an NFORCE2 
issue... Or too many IRQ-handlers on the same IRQ...

I wish I could do something more to help. Unfortunately it is almost 
impossible for me to do tests on the Intel system (as it is a production 
system) - though I might be able to try some things late at night in the 
weekends ;-)

Guess at this point it would be nice to be able to reproduce the 
behavior on an Intel system...

Best regards,

Peter
