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

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

Let me guess: a Lucent Orinico PCI adapter, right? It should work with
linux-2.4.6, I submitted a patch for 2.4.6-pre8 (or so) and it is
included in linux-2.4.6. I currently have it working on two non-SMP
systems (ALi 1541 and Intel 440FX chipsets).

Make sure that the Cardbus driver is not a module. IOW: your kernel
configuration should have these lines:
#
# PCMCIA/CardBus support
#
CONFIG_PCMCIA=y
CONFIG_CARDBUS=y
# CONFIG_I82365 is not set
# CONFIG_TCIC is not set

Actually it is something compatible from ELSA.
I tried your suggestions and it didn't work. On your machines, does the card
get an interrupt from the bios during init?
My Bios (PCI v2.1) only prints CardBus Adapter, no IRQ is assigned.
I already tried different slots. I guess it's a bios problem but i'm interested
to make it work without the help of the bios. At least the bios is only
a pice of software...

Did that. Interesting messages during kernel boot:
PCI->APIC IRQ transform: (B1,I0,P0) -> 16
got res[20000000:20000fff] for resource 0 of Texas Instruments PCI1410 \
PCcard Cardbus Controller
Linux Kernel Card Services 3.1.22
options: [pci] [cardbus]
PCI: Enabling device 00:13.0 (0000 -> 0002)
PCI: No IRQ known for interrupt pin A of device 00:13.0. Probably buggy MP
table.
Isn't it possible to assign an interrupt to INT A of this device ? IOW, fix
what
is considered a buggy MP table ?
Yenta IRQ list 0000, PCI irq0
