[ILUG] Linux and Shared IRQs

[ILUG] Linux and Shared IRQs

Hi,

I work on a Sony Vaio pcg-z1rsp which I am trying to get set up 
correctly under Linux.

First off its a centrino. However I have compiled the drivers from 
sourceforge but I am still get unresolved
symbols. But I think the main problem is the shared irq setup.

My firewire, usb, sound, video, modem and pcmcia controller all share irq 9.

This sounds mad I know but thats the setup as reported by both Linux and 
Windows.

Anyway, Linux is not happy. It won't start usb or firewire at all and 
the sound  plays very crackly.
When I try and modprobe any of the drivers all I get are complaints 
about irq conflicts.

I have tried a 2.4.20-8, 2.4.25 and a 2.6.4 kernel. None of them can 
handle it.

Is there something I should set  in menuconfig to get this working or is 
there a patch somewhere?

Keith
