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.
