Adaptec 1530P insists on IRQ 12
Curtis Rempel
I've searched everywhere but can't seem to find a solution to this problem
I'm having with my 1530P card using aha152x
I've set it in the SCSI BIOS to use IRQ 11 as my PS/2 bus mouse is on IRQ 12
and there doesn't seem to be any way on my Compaq 6150e to change it to
something else.
Still, when I load the module and explicitly specify IRQ 11, it complains of
"trying software interrupt, lost" and "IRQ 11 possibly wrong, please verify"
If I insmod it with IRQ 12, it is happy and my SCSI disk works just fine
except of course gpm complains of device/resource busy.
/proc/interrupts doesn't show anything on IRQ 11 although I understand that
it doesn't necessarily mean that something isn't using IRQ 11.
I have also tried setting the Compaq BIOS IRQ 11 as "used by ISA card" but
this had no effect (power cycle of course).
It would seem that the SCSI BIOS is the only method of altering the IRQ for
this card, although I have observed a jumper block on the card but don't
know if it is related. I know the DIP switches only affect the I/O address
and plug/play.
Anybody know what is going on here?
Thanks in advance.
