Thanks Andrew.  I just tried doing this with 2.6.18-rc4-mm3 and it
hung again.  I also tried booting with irqpoll and pci=routeirq but it
made no difference at all.  I got the following with irqpoll:

   irq 17: nobody cared (try booting with the "irqpoll" option)

   Disabling IRQ #17


I'm going to try and upgrade the firmware on my RocketPort 133 from
1.21 to 1.22 to see if that makes a difference, but otherwise there's
not alot I can do here.

Any more information I can provide?
