I'll give that a try. > Also Trying disabling shared IRQs Well, this isn't gonna work. There are not enough IRQs for this to work, and shared interrupts are a feature of PCI peripherals. I really don't want to have to do this. Shouldn't the driver check to see if the board is even enabled to generate interrupts before falling into the service routine? How about checking the INT_MASK register at 0x104 to see if we've even enabled interrupts? I don't seem to see a simple interrupt asserted bit in any of the status registers, which is too bad. I guess a mask of the appropriate bits in the interrupt status register would do it. louie
