[cobalt-developers] Problems with Raq3i and AVM Fritz PCI ISDN card

[Chris Audley <chris@xxxxxxxxxxxx>]

I wonder if anyone out there can help me with trying to get an AVM Fritz PCI
ISDN card working in a Raq3i. The card is being recognised by the Raq, but
when I try to start the ISDN driver (hisax), it fails with errors about not
being able to receive interrupts.

Card is recognised by the Raq in the PCI device list:

  Bus  0, device  20, function  0:
    Network controller: AVM A1 (Fritz) (rev 2).
      Medium devsel.  Fast back-to-back capable.  IRQ 9.
      Non-prefetchable 32 bit memory at 0xef00 [0xef00].
      I/O at 0xffffffe0 [0xffffffe1].      



But a 'modprobe hisax type=27 protocol=2 id=0' results in the following
in /var/log/messages:

/proc/interrupts shows no sign of the AVM card.

I've tried this with the stock kernel sources on the Raq and with the lastest
isdn4linux CVS snapshot, but with the same results.

Same card and CVS snapshot works fine on a desktop PC with a 2.2.12
kernel and a 3com PCI ethernet card (3c59x driver) works fine in the Raq3i.

Has anyone out there got any ideas as to why the interrupts don't appear to
be working with this card?


TIA,
