One other thing to check, which is rare but I've seen before with your symptoms, is a controller that's not listed in the driver's PCI ID list. The chip onboard is a 1068e but if Supermicro used a nonstandard PCI ID, the driver wouldn't recognize it. -- Drew "Nothing in life is to be feared. It is only to be understood." --Marie Curie
