In any case, you don't really want it because iof the interrupt conflict. Try using full hints for it. I would have expected just the "disabled" hint to work though. Try leaving out the irq hint. This should give polled mode for sio (and thus no conflict with other devices using the irq) and works for the plain isa case. I suspect that there is a problem with resources getting merged (can the irq resource be supplied by acpi even when it is intentionally left out of the hints?). I avoid these problems by not using acpi. > The SMC Ultra card exists on 0x280 irq 10 0xd8000. Has current > dropped ISA support (which was hinted at in the GENERIC/80386 > thread)?
