Could you give alsa-info.sh output (run with --no-upload option) on the working (2.6.36.x) kernel? Also, load snd-hda-intel driver with probe_only=1 option on the latest 2.6.37 kernel and give alsa-info.sh output as well.

Thank you for taking the time to make bug reporting for alsa so easy for us. Thanks. The patch below should fix the issue. It's now in sound git tree and will be included to the upstream in the next pull request. Created attachment 43382 [details]

Created attachment 41702 [details] Full kernel log I am using linux-image-2.6.37-rc7-amd64 (2.6.37~rc7-1~experimental.1) from debian experimental. My motherboard is Intel D946GZIS. During boot I get this oops and sound does not work. It used to work on 2.6.36 and before. Below is the relevant part of dmesg. I also attached the whole thing (kernel.log). I am new to submitting kernel bugs so I apologise beforehand if I am missing any info. Please let me know if you need anything else.
