[mythtv-users] mythdora 3.2 + air2pc rev1 setup problems - resolved

The card is working now.  I threw it into a windows box and it 
immediately caused bsods that seemed to be irq related.  I noticed on 
the windows box that it was trying to use irq 9 along w/ almost every 
other pci card in the system.  In that box's bios I can force a given 
pci slot to use a particular irq.  Once I forced the slot it was in to 
use irq 11 the bsod stopped and the card worked.

On my mythdora test system I can't manually assign irq's to particular 
pci slots in the bios so I just swapped pci slots and the card was 
recognized properly.

For future reference, here is the relevant part of the dmesg when it 
loads properly:
