You have assigned a free IRQ to the pcic and it's now working fine. The next step is the interrupt of the Xircom card, itself. Under the current pccard software the IRQs are assigned from a list in the pccard.conf file. You need to look for another free IRQ to assign to the xe device. The best thing to do is to scan the outputs of dmesg and vmstat -i and see what IRQs are in use. IRQ 2 and 13 are always unavailable. Then edit/create /etc/pccard.conf with a line reading irq 5 9 (replace the numbers with the free IRQs you have found.) This should do the trick, although it is possible that your laptop will need the iomem range adjusted, too. This is all a real pain, but once you get it, you won't have to worry about it until V5.0 comes out which will replace the whole mess with something that works far better (I hope). Good luck! R.
