I'm running an Opteron 2378 (2.2GHz) quad-core processor running a
SP5100 southbridge, equivalent to an SB700-class chip. I am having the
exact same problem and I've tried two different pairs of drives,
different makes and models (started out with two WDC Caviar Green 750GB
drives, moved to Seagate 1TB Barracudas (no XT, no LP)).  It makes no
difference; the system still crashes.  For the record, the board is a
Supermicro H8DI3-i-F board.

Likewise, the time and manner of problem is highly unpredictable.  It
appears to be a case of interrupt loss, and there is otherwise no
hardware issue that I can discern with the drives themselves.

I have yet to try pci=nomsi, but I have tried with pci=noacpi with
identical results, a crashed system after a random period of time.
However, I have my doubts whether this will work since, apparently, the
AHCI controller is not using MSI-based interrupts (it shows AHCI
connected as a IO-APIC-fasteoi interrupt).  The ethernet controller
does, however, use a PCI-MSI-edge interrupt, as does the PATA
controller, which I do not use.  If need be, I can furnish all the
necessary data.  I just need to know what is needed.

Also, will the pci=nomsi item actually help me?  I ask because, as I
indicated, this controller apparently does not use such an interrupt.
