Hi

for the history : i am having a issue with ACPI and IRQ`s ( i believe )
i have a configuration where sound ( ali5451 ) , eth0( realtek 8139) and 
usb ( usb-ohci) are using IRQ 5 .
Until now what happens is that when i used 2 out of these 3 devices at 
the same time the unit locked hard .

Now i am able to set eth0 to IRQ7 and a first stress test with 600MB 
dowload and playing songs worked fine .

I am using now 2.4.22 + acpi20030916  + the initrd patch to use my own 
DSDT .

I reached that now in sent the LNK1 in my DSDT to IRQ 7 .

Unfortunatly the systems still uses IRQ 5 for the other 2 devices 
although i also did change the LNK8 and LNKU  at the DSDT ( tryed 6  and 
11 and 7 ) .

find attached my data of the unit ..

can somebody tell me why it ignores my changes to LNK8 and LNKU in my 
DSDT and still uses IRQ5 ?
i am also curious why certain LNK`s are parsed twice ???

thanks

Rob
