I've been having hdaudio/mixer issues for months, but this is the first time I've run w/ a debug kernel -- I don't have the prev. PR, but will combine these (seems appropriate) when I do. I do want to get this out as yet another datapoint though, as this flaky audio/mixer behaviour has been going on for some time.
>How-To-Repeat:
Run DEBUG -current kernel on Thinkpad T410.
