no sound with 2.6.5 kernel - is it a bug?

[Slaven Peles <slaven.peles@physics.gatech.edu>]

Hi,

Some people have reported that upgrade to 2.6.5 solved their sound problems, 
but in my case 2.6.5 "turned" sound off. I am running sid with debian 
precompiled kernel (2.6.5-1-686), I use alsa, and I have Intel's onboard 
sound card:

0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB (ICH4) AC'97 
Audio Controller (rev 03)

If I boot kernel 2.6.4 or 2.4.24 with precompiled alsa modules, sound works 
fine. For each kernel all modules load properly. Is there some configuration 
option that I should change in order to enable sound with 2.6.5 kernel or I 
should just file a bug? 

Many thanks,
Slaven
