I'm modifying a serial driver that has for years worked happily with QNX6 and the PCI-X bus interrupts. An Express (PCI-
E) version of the card has now been released and everything in the driver seems to work (with new device ID's etc 
accommodated) except the interrupts. Is there anything I need to do differently to catch the PCI-E interrupts? 

Thanks,

Geoff.
