SubjectACPI munges IRQ routing in 2.5.58 on HP3000 U3 (fwd)

Hi Andrew, lists,

(2.5.59 has the same problem, I've just tested)

After extensive help from Justin Gibbs (the aic7xxx driver maintainer)
I've determined that the reason the SCSI subsystem fails in 2.5.58 is that
the IRQ routing setup by ACPI is wrong. Quoting Justin after sending him
verbose debugging from his driver:

<quote>
The output has confirmed what I had suspected. The card is not
getting interrupts. My guess is that some change in the interrupt
routine code in 2.5.X is not working correctly on your system. To
completely verify that, you could try dropping in 6.2.27 into a
2.4.20aa2 kernel.
[snip] You might also try to influence interrupt routing in your
system by playing around with the "apic" and "acpi" kernel options.
</quote>

I didn't try 2.4, but *did* try booting with pci=noacpi which solved the
problem for me.

I've attached the bootup log with and without the pci=noacpi option
(gzipped) so you can see the differences.

Here's the relevant 'diff' of the two files:
