Did you try to jumper the GA-410 as a second controller and assign a
IRQ different from 9 to it? This is only possible if the card is
configured as a second SCSI controller (Jumper JP3 to pins 2-3).

I have the same configuration as you and encountered the very same
problems. But this trick solved the problem and the system runs fine
(and very stable).
