Use 4 2-port cards for your 8 drives and only one drive per cable. It is possible, and I've had it happen to me, that a hardware failure on a failing drive can cause loss of access to the 2nd drive on the same cable. Fortunately when it happened to me, the disks weren't in a RAID set and I didn't lose any data on the other drive, but if the disks were in a RAID set, then you'd have a 2-disk failure on your hands, and unless it was RAID-6, then you'd be shafted! I was about to suggest running with noapic, but you've already tried that... You might also want to see if the motherboard has a way to turn the APIC off too. I had that on one Athlon mobo, and running it all in PIC mode kept it going much better. Also experiment with PCI slot locations, although with 4 PCI cards, you might not have much luck, depending on your motherboard. Try to get each card on its own interrupt if at all possible. Some BIOSes can help fix this for you, some can't....
