Bug description:
  Binary package hint: kernel-image-2.6.22-8-generic-di

  I chose to file this under the current Gutsy kernel, but this issue
  has plagued me since Dapper.  Ever since Dapper my laptop wouldn't
  shut down properly.  I would get the infamous "will now halt" message,
  but my computer would never completely shut down.  Today I found the
  culprit: the snd_hda_intel module.  If I manually remove this module
  (rmmod snd_hda_intel) before shutting down everything works perfectly.
  My laptop is a Toshiba Satellite A105-S2716.

  I also came across a post from bug #43961 that confirms the same behavior. Coincidentally, he has the same model laptop I do:

  Workaround:

  To work around this problem, I created an init.d script to run at shutdown.  All the script does is remove the snd_hda_intel module at shutdown (rmmod snd-hda-intel) and things work smoothly.
