Hi all,

i have a PCI Cardbus Bridge which is getting no interrupt from
the bios and during kernel boot. Is it possible to use the card anyway ?
Maybe assign an interrupt manually ?

The details:

kernel 2.4.6 smp machine

device in question:

00:0e.0 CardBus bridge: Texas Instruments PCI1410 PC card Cardbus Controller 
(rev 01)
        Subsystem: SCM Microsystems: Unknown device 3000
        Flags: bus master, medium devsel, latency 168
        Memory at 20000000 (32-bit, non-prefetchable) [size=4K]
        Bus: primary=00, secondary=02, subordinate=05, sec-latency=176
        Memory window 0: 20400000-207ff000 (prefetchable)
        Memory window 1: 20800000-20bff000

        I/O window 1: 00001400-000014ff
        16-bit legacy interface ports at 0001

I enabled DEBUG in pci-i386.h and get the following messages:

Any clues ? Should i send more details ? If yes, which ones ?
