SubjectFrom 2.6.24 -> 2.6.25, lost audio (snd-hda-intel)
Motherboard: A-Bit AWD9-MAX
Using 2.6.24, everything is fine, using 2.6.25, no audio (used make
oldconfig)..
Kernel configs used attached.

I did not see any errors of any kind it just did not play any audio, I
booted back to 2.6.24, everything working fine again.

The second one I enabled debugging.
