Buy a PCI-X SCSI/GigE card, and use that instead of the on-board one?
Neither of our S288[12]'s are sharing any IRQ's; we're using Adaptec
2120S RAID cards, and they have a bus and IRQ to themselves.

MySQL performance still sucks on our FreeBSD machine, but that's an OS
problem; the hardware looks fine to me.  If you have suggestions for a
better dual Opteron motherboard I'm all ears :)
