The underlying problem here is that the pccard model does not provide any way for pccardd (userland) to access the current IRQ usage (kernel). So pccardd depends on you to give it an IRQ that will work. Your problem is probably caused by the fact that in the GENERIC kernel (and others), pcic1 likes to use IRQ 11. Even if you disable some IRQs, it seems that it is still used up in the kernel. So you have to pick an IRQ that is definitely not used for anything at all. For me, on my Dell Inspiron 7000, IRQ 9 works best for the 3CCFE574BT. Be sure to test all the IRQs until you get one that works for you. > # ping 192.168.64.3 > PING 192.168.64.3 (192.168.64.3): 56 data bytes > 64 bytes from 192.168.64.3: icmp_seq=13 ttl=255 time=911.308 ms > 64 bytes from 192.168.64.3: icmp_seq=14 ttl=255 time=1901.416 ms > 64 bytes from 192.168.64.3: icmp_seq=15 ttl=255 time=891.487 ms > 64 bytes from 192.168.64.3: icmp_seq=16 ttl=255 time=1881.523 ms > 64 bytes from 192.168.64.3: icmp_seq=17 ttl=255 time=871.616 ms > 64 bytes from 192.168.64.3: icmp_seq=18 ttl=255 time=1861.925 ms > 64 bytes from 192.168.64.3: icmp_seq=19 ttl=255 time=851.989 ms > [...] Classic IRQ conflict symptom. > in this machine, nor another available laptop in which to test the 374B.
