I'm having problems with 2.4.2-pre3 and IRQ conflicts. Last kernel that
I tried and worked without conflict was 2.4.0-test11. Here are the
relevant messages that I get:

I enabled more debug messages, so here is the updated messages. I also
noticed that ACPI is trying to use IRQ 9, which the soundblaster is also
trying to use.

That seems to indicate acpi is freeing a free irq. Turn ACPI off. Its a
good bet it will fix any random irq/driver problem right now

Looking at this a bit further, I realised that when the sound driver was
compiled in the kernel, it is initialised before ACPI. The BIOS has
assigned IRQ9 to ACPI, but the PCI code does not know this because of:
PCI: 00:07.3: class 604 doesn't match header type 00. Ignoring class.
The ISAPnP code then assigns IRQ9 to the sound card, causing the ACPI
code to fail to allocate it. If I compile sound as a module then the
ACPI driver grabs IRQ9 and the sound get IRQ7.

Hi Brian,
please test this patch with ACPI enabled and sound driver compiled in kernel.
IMHO it should fix this problem.
Best regards.

Hi Brian.
I'm sorry, patch itself was not attached in previous post :(

Yes, this does fix that part of the problem. There is still the matter
of the class code being wrong but I have ideas on how to fix that.
