Hi Martin,
i spent few last nights with my Extensa. This notebook has PCI 2.1 wich
works only under m$ window$ :-(. I tried many version of kernel, 2.2,
2.4 and 2.6 tree and nothing helps me. I tried pci=bios pci=bios,biosirq
kernel options, PCI=BIOS instead of ANY...
Result is always same:
PCI: No IRQ known for interrupt pin A of device 00:04.0.
this cause for example that PCMCIA doesn't work. See attached dmesg log
and other files for details.
In Window$ everythink works OK and IRQ routing table is get from PCI
BIOS.
Any ideas?

I've got the same problem with the Cardbus bridge on my old Thinkpad 760ED - I
think your laptop is as old as mine (Pentium 166 - 1996 or thereabouts).
The problem with mine is that the Cardbus bridge doesn't get a vaild IRQ written
into the chip by the BIOS, and Linux relies on the BIOS to do it on older
machines. I haven't found an answer yet - I'm just getting into this stuff
myself, and don't understand PCI well enough to code a fix. It is good to know
that it is not an IBM-only problem.

Just out of curiosity - does lspci -vvb show the interrupt pins on the Cardbus
bridge routed to IRQ 255?
If so, it might be a problem with the TI bridge chip. IIRC, that's the same model
chip as in my laptop.

Hi Jim,
thank you for reply! Nice to hear that you have similar problem. You
have right, my notebook is same old as yours, pentium 166, maybe
1994-1997. I have TI PCI1130 cardbus bridge. You have right, pin is
routed to IRQ 255. See attach file. But i see same behaviour on IDE
device. Strange is that this works fine under window$ :-( which says
somethink as "interrupts table get from PCI 1.2 bios". I don't know how
far i can believe it.

Hi all,
Last night i solved this problem. It cause by crippled PCI chipset
parody called ALi and his perverse undocumented "features". I think that
use ISA bridge as IRQ router if we haven't any router is guite good idea.
Everythink with this patch works fine even though i have different irq in
win. See attached logs.
Jim, can you try this patch please? I assume that you have some kind
of ALi chipset too. Maybe this solves your problem too.
Martin, Marcelo, please aply :-).
PS: is here anybody who have relevant datascheet?
Regards,

Naah. I have a piix chipset. My problem (per David Hinds) is that my laptop is
even more b0rken than yours - IBM never hooked up the PCI INTx lines on the TI
1130. My laptop never worked with Cardbus stuff - even in Windows.
He reccommended the external pcmcia_cs package for my system - there's a dummy_cs
module in there (2.4 only, though) that should fix my problem.
Thanks,
Jim

That's pity :-(. So i don't help you with this because i don't have
similar IBM notebook. Hmmm you should beat out datasheet from IBM :-).

Yes, external pcmcia_cs drivers works in this situation. But you need
working irq for e.g. cardbus card that have only pci driver in kernel. I
needed this because realtek_cb work bad and i would like to use cardbus
usb controller and some wifi card.

It looks that you have same problem and kernel doesn't find IRQ
router. So try attached patch (for 2.6.9 and added your bridge) if it helps.
I think that it may help (look at dump_pirq results).
You can try turn on DEBUG (in file arch/i386/pci/pci.h) and see debug
messages on screen.

That patch comes too late in the PCI init sequence for my machine.
pirq_find_router() (where your patch goes) depends on pirq_table being set up by
pirq_find_routing_table(). When I put in the debug statement in the attached
patch, I got the "PCI: No Interrupt Routing Table found" message. Since
pirq_table wasn't set up, pirq_find_router() is never called. Let me look at this
some more (got vacation this week, so I can finally devote some time to this.)

It's a BIOS problem. Linux is capable of retreiving the pirq table using BIOS
calls, but the table the BIOS returns does not have entries for the Cardbus
bridge. I think I might be out of luck. Lemme go do some research, and see what
I can dig up.
