IRQ routing conflict

[Marko Rauhamaa]

A google search revealed
(http://www.cs.helsinki.fi/linux/linux-kernel/2001-44/1775.html)
that you have recently had similar trouble as I have with PCI
interrupts. Have you found a resolution to the trouble?

My new laptop is mostly working, but I can't get my sound card to
produce a sound. I'm suspecting that the sound driver is not receiving
interrupts. I can hear the clicking when the driver is loaded -- and I
have used aumix to set the volume. Both ALSA and OSS (commercial) fail
the same way.

I'm running 2.4.17 with SuSE 7.3.

Here's a snippet from dmesg:
========================================================================

Should I return the laptop to the shop? (It's a Compaq Presario 700Z).
