Hi

sorry for the question since i saw that this ( or a similar ) topic is 
already discussed , but i had the acpi-devel
list running on digest mode and it is hard to follow a topic with that .
Now switched back to to non-digest .

My issue is :
Can i fix a faulty IRQ-Routing via DSDT ?
My unit has not a IO-APIC but a normal XT-PIC
it also looks that some IRQ`s are provided already by the BIOS and so 
are active already .

So my unit ends up having eth0(realtek8139), sound ( ali5451) and usb ( 
usb-ohci) having IRQ 5
when i then do a stress test like sucking a file via eth0 bigger then 
10MB AND playing sound or using USB mice or so  , i get a very cold 
artic freeze ( brrrrr) of the complete system without and debug message 
in any log.

this is a reproducable error and i blame my BIOS to be the error .

So i need to test if it makes a difference to provide every device a 
different IRQ .

I read some DSDT`s and also checked the ACPI 2.0 Reference
i tryed to change the available IRQ`s for the specific LNKX`s to 7 or 11

but it always ends up that my system
enable`s IRQ 7 to IRQ 5 .....

What can i do ...
btw .. i applied the "reading dsdt from initrd " patch and so i can 
quickly load different dsdt `s !

find attached my dsdt

i am using
2.4.21 + acpi20030619 + swsusp 1.0.3 + preempt ..and so on
I also use a nice patch to setup.S from Bruno Ducrot which fixes already 
a bug so
the the ACPI Tables are actually found and loaded !!!

Cheers Rob
