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).

When using ALSA, be sure to *unmute* the channels with alsamixer (aumix
won't do).

I've got a Dell Inspiron 3500 where the sound works fine on the first boot
but the IRQ gets lost after an APM suspend, and even unloading/reloading the
module doesn't help. (The I/O addresses are still valid, but it gets no IRQ.
KDE has no sound, from the command line it loops playing the same segment
over and over complaining about timeouts...)
It's been doing this for a year. I've mentioned it here a few times before.
I've played around with setpci and such, but haven't been able to fix it. I
just reboot when I want sound. The bios sets it up right (on a cold boot,
not returning from APM). Linux (even 2.4.17) does not.
