Do you have 2.6.39 kernel messages? I see the warnings in your dmesg below in 3.0* kernels. Did you get it with the working kernel as well?
Yes, and this one appears in all logs (as said in Debian bug). See http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=15;filename=dmesg-2.6.39-2-... for the full dmesg of Debian's 2.6.39.

Also, you can replace the files in sound/pci/hda/* from 2.6.39 kernel tree. If this fixes the problem, it's a sound driver bug. If not, it's anything else, e.g. the problem in more core side, e.g. IOMMU like above or the timer change, etc.
Hey, that was a great idea! I reverse-patched sound/pci/hda of 3.0 with 2.6.39.3, and it fixes the problem! :) I attach the dmesg of that version (3.0 with 2.6.39.3's sound/pci/hda) if it is of any use for you.
