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-amd64;att=1;bug=635362
for the full dmesg of Debian's 2.6.39.

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.
