Hi,
Below some more info on my two systems:

The promise card has IRQ 18 all by itself
And the machine that does have problems, what chipset does it have?

The promise card is sharing IRQ11 with usb, the other libata device, and
nForce2 (wonder what that is?)
I'm actually beginning to think there's some PCI compatibility breakage
somewhere, as I too see sata_promise working fine in some machines but
not in others. Alas, my knowledge of PCI tweakables is close to nil.
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
