it's not hung, it's just really really sloooow. caught missed irq means that it's trying to forge ahead even though the ide irq has been somehow misrouted. my ide driver tries to do its best in these cases, since this is a very common problem. do you have a recognized southbridge? there should be a dev file /dev/mpirq (or nompirq if mp irqs are off) that describes the mp table. sometimes you'll see that there are two mappings from bus irq to processor irq that are the same except for the i/o apic output pin. without the routing tables, you don't know which one is correct. it would be nice to be able to override irqs in plan9.ini. - erik
