Re: [proaudio] 2.6.17-rt8 kernel does not boot

[Dominique Michel <dominique.michel@xxxxxxxxxxxx>]

I think at it is a hardware IRQ sharing problem. RT-kernel don't like
it. You have 2 devices that share the same IRQ. 

You must look in the bios to see if you can reassign the IRQ, or try to
move some cards from slot to slot. You can also boot the vanilla kernel
and look at the output of 

cat /proc/interrupts

It will show you the shared IRQ. acpi=off is a good option with a
realtime kernel. The acpi system will be disabled and it will spare an
IRQ that will be avaible for other hardware.
