dmesg log of the stack trace (in a git bisect session)

Hi.

I have been using the stable lineage of kernel 3.8 and it started giving me
stack traces whenever X closes/terminates (this includes logouts or
hibernation) and my kernel gets tainted.

I laboriously bisected the problem and it is (surprisingly to me) on a commit
by Takashi Iwai on ALSA/hda. This commit was backported to the 3.8 tree and
this is why I encountered it on that version (Debian still doesn't have a
precompiled 3.9 kernel).

I am attaching the dmesg log and I can provide any kind of information that you
think that may be useful for debugging.


Thanks in advance,

Rogério Brito.
