Can you try booting your kernel with the acpi=off argument and see if that has
the same results?

Also when booting with ACPI enabled, can you show the output of:

amixer scontents

amixer output when system booted without acpi=off

If a dev could please review the following upstream bug: 

http://bugzilla.kernel.org/show_bug.cgi?id=8273

I think it is directly related to this bug. 

The amixer scontents output matches the upstream bug in that there is no
'Master' control.

yes it's the same bug

Once verified, could a Dev please add the following:

1. Status Whiteboard: watch-linux-bugzilla
2. URL: http://bugzilla.kernel.org/show_bug.cgi?id=8273

At that point, we'll watch the upstream bug.

Gregorz, what happens when you try and play a sound? The messages you listed in
comment #0 appear during boot.

When you try and play a sound, does your audio app give an error message? Or
does everything seem to function as normal, except that you can't hear
anything?

Which kernel is the dmesg output in comment #4 from? I'm interested to see
dmesg output from the working 2.6.20 kernel.

Jeremy, nice find, that appears to be the same bug.

Grzegorz, this is currently our only completely unsolved 2.6.21 regression. I'd
really appreciate the info requested in the above 2 comments so that we can
feed more info upstream. Thanks in advance.

this is dmesg from gentoo-sources-2.6.21

dmesg-2.6.20-r8

heare isw gentoo-sources-2.6.20-r8 dmesg. on 2.6.20-r8 intel-hda driver works
fine :>

Thanks for the info. One more question: which hardware are you using here,
specifically which mainboard?

I suggest you create a kernel bugzilla account if you don't already have one,
and add yourself to the CC list of the upstream bug so that you are notified
when patches are available (or more info is needed). If not, I'll try and do my
best to notify you on this bug when something happens, but no promises...

Please apply this patch to 2.6.21 and see if it fixes the problem.

Thanks for the quick testing, sent that upstream
