Sorry but i did set all this values in the init script (even before proc 
with the -H1 switch
of setpci) of my redhat 7.1
but the output of dump_irq ( i've read about this on the 
kernel-mailing-list )
looks rather strange.

output of lscpi -vv -xxxx attached toot

Any Hints?

* 2.4.7 and setpci no go

Hi,

i have a problem with my new Athlon board and a really silly bios, which 
assigns
all my interrupts of usb,audio,eth0,bttv to irq 11

i have to turned off pnp aware OS in the bios
and i can set  via setpci the irq as the examples below indicate.

Still you can see in the example that the Line with the IRQ shows 11.
and when i insert for example the AC97 driver of ALSA io gets interrupt 11.

Same situation for usb, eth0, bttv.

So I am lost now :(
Is this a kernel bug or is there a kernel parameter which i have to use?

Regards
Dietmar
