Check the order of driver loading. This affected me a few kernels ago. Found that one needs to force the order of driver loading in modprobe.conf HTH
The modprobe.conf is looking like this:
========================
alias eth0 e1000e
alias scsi_hostadapter ata_piix
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || :
; }; /sbin/modprobe -r --ignore-remove snd-hda-intel
alias wlan0 iwl3945
=======================
The same configuration is used for both old (functional) and new
(nonfunctional) kernels
What are your suggestions regarding the order of drivers loading ?
I found that there was another module loading before the snd-hda-intel
thus I added index=0 to the one I needed and index=1 to the other module
that seemed to get in the way.
the clue was looking under System>Administration>Sound Card Detection
and seeing the Audio configuration dialog > Settings tab - it showed my
desired sound card as number 1 rather than 0 with another item as number
0 (one I did not even know was on the computer).
Took me a recompiled kernel and hours of wasted time. Old kernels all
worked fine - thus I thought it was a kernel patch problem - removed all
the related patches and still no joy.
I do not know what they are doing to the kernel but over time the
loading of modules, order of disk detection etc is becoming much more of
an issue.
HTH YMMV
