2.4.0-test12: PCMCIA IRQ assignments?

2.4.0-test12: PCMCIA IRQ assignments?

[indyj]

Hello,

I have a Sager NP9820 laptop with an ALI chipset and a TI PCI1251BGFN
PCMCIA chipset.  For some reason, when I use the yenta module under 2.4.0,
it gets an incorrect IRQ assignment.  It uses IRQ11, which is also used by
my ATI Rage Pro card... therefore, when you install this module, the
machine locks up.

If I use the pcmcia card services under 2.2.16, then the PCMCIA bridge
gets a correct assignment of IRQ 10.  I've poked around a bit and haven't
found a way to force the 2.4.0 module to use a specific IRQ... is there a
way to do this without hardcoding it?

Otherwise, this is an ideal laptop to run Linux.

Thanks,
--J

Do you have a sound driver loaded?  I can use my CardBus Ethernet card
only without a sound driver, then the CardBus bridge and Ethernet card
show up on IRQ10.  Mysteriously however loading the i810_audio driver
(for a 440MX chip) moves the bridge to IRQ11 (the same as the 440MX).

No lockup, but the bridge and Ethernet card don't work then.  I'd be
interested what happens in your case.

More specifically, as the PCI code enables the 440MX sound device it
logs that it uses the same IRQ as the cb bridge, meaning the IRQ changed
already.  This is 2.4.0-test12.
