The shutdown gets stuck when it tries to unload the modules related to ALSA; specifically module "snd-hda-codec-analog" is the troublemaker. "lsmod" indicates this module is "Used by 1" but doesn't give any clue about who is using it. I had no problem with 2.6.28. Bisection identifies the bad commit as 1289e9e8b42f973f2ab39e5f4f2239ff826c27e9, "ALSA: hda - Modularize HD-audio driver". Indeed before this commit the offending module did not exist.
