It took me some time to find out that this very IRQ line is used by the BIOS! Under the BIOS setup menu ``Green PC Features'' there is one line ``Non_SMI CPU support: [Generate IRQ 10]'' The only other option is ``Generate IRQ 15'', which is already used by my secondary IDE controller. So I lost one valuable IRQ because of this silly ``feature''. BTW. Anyone knows what they mean by ``Non_SMI CPU support''? I know of one other case, where a teles 16.3 would not interrupt at IRQ 9. Now it's using IRQ 5 and working fine. (No, I did not try to write IRQ 2 into the latch during probe/attach) The lesson learned: If your ISDN (or whatever) card doesn't work, give IRQ 5 a try. Of course, if already used by another card, remove this card and disable the driver in the kernel.
