: The ports are enabled in the BIOS and do seem to work.. mostly. I have had
odd

: I have another [custom] driver that is based on sio.c and it shows the same

: I have tried playing with various ACPI & ATPIC settings in the BIOS but no

: I have updated to the latest BIOS but it had made no change.

: Hmm actually I just looked through the code.. It appears that this happens
: because isa_irq_pending() is a noop unless isa is in the kernel, and it isn't
: in GENERIC. Perhaps those tests in sio.c should be conditionalised on isa
: too?
isa_irq_pending can only really be called on isa bus attachments...
Why don't you have ISA in your kernel. I thought it was still required.
