I don't think that's a regression, nor really a bug. It looks cosmetic, and likely to be fixed, but not really worth worrying about.

This went through bisection, but looking at the email log, I tend to suspect that maybe Trenton marked some versions good even though they weren't (because they got versions numbers from v2.6.27), and didn't realize that that messes up bisection in a big way.
The bug _sounds_ like some deadlock due to lock problems - the shutdown path often triggers locks that no other path really cares about. And we had some lock problems in the sound subsystem that got fixed post-2.6.28, for example.
And it looks like the problem is somewhere in sound shutdown:
12181 delete_module("snd_hda_codec", O_RDONLY|O_EXCL) = -1 EAGAIN (Resource temporarily unavailable) <0.000011>
So commits like 91054598f794fb5d8a0b1e747ff8e2e8fc2115b3 ("ALSA: pcm_oss, fix locking typo") might explain it.
