The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release.  As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

1)  If you are comfortable installing packages on your own, the linux-
image-2.6.27-* package is currently available for you to install and
test.

--or--

2)  The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer
2.6.27 Ubuntu kernel.  Alpha5 is set to be released Thursday Sept 4.
Please watch http://www.ubuntu.com/testing for Alpha5 to be announced.
You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the
bug reported here or if the issue remains.  More importantly, please
open a new bug report for each new bug/regression introduced by the
2.6.27 kernel and tag the bug report with 'linux-2.6.27'.  Also, please
specifically note if the issue does or does not appear in the 2.6.26
kernel.  Thanks again, we really appreicate your help and feedback.

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:
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/43961/comments/157

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.
