linux 2.4.x doesn't detect irq for pcmcia card socket

[Matthieu PATOU]

I'm facing an error which seems not frequent in linux :Dec  7 23:20:35 mobile kernel: Linux Kernel Card Services 3.1.22

2 IRQ are not found in the irq router table (according to the kernel)

Dec  7 09:39:34 mobile kernel: IRQ for 01:02.0:0 -> not found in routing table
Dec  7 09:39:34 mobile kernel: IRQ for 01:02.1:1 -> not found in routing table

This trouble cause me this message whith PCMCIA:

Dec  7 23:20:35 mobile kernel:   options:  [pci] [cardbus] [pm]
Dec  7 23:20:53 mobile kernel: IRQ for 01:02.0:0 -> not found in routing table
Dec  7 23:20:53 mobile kernel: PCI: No IRQ known for interrupt pin A of device 01:02.0. Please try using
 pci=biosirq.
Dec  7 23:20:53 mobile kernel: IRQ for 01:02.1:1 -> not found in routing table
Dec  7 23:20:53 mobile kernel: PCI: No IRQ known for interrupt pin B of device 01:02.1. Please try using
 pci=biosirq.

Adding pci=biosirq (in the append parametter of lilo) doesn't change the problem 

The hardware is an VAIO PCG QR20 with an i815 (EM i think but not sure sony has not respond to my questions)

I noticed that the problem was nearly the same and was solved by adding the router name into the irq router table (plus some magic code
) i'm not sure this will solve the problem but dump_pirq and PCI code find a 8086:122e router but in fact it's a 8086:244c ...

Well the trouble i get with this is that system often hangs when inserting or ejecting PCMCIA card (i've spent two weeks playing with david hinds pcmcia modules and options cb_pci_irq and pci_irq_list for instance without great results ...)

So if you know how to solve or to progress in email please feel free to respond to this mail 

Btw my bios force the use of ACPI and i have not joined the result of dump_pirq maybe it is needed ?
