Comment 55 for bug 21256

As I said before, the dpatch works perfectly for me but I have noticed a problem
related to it. Now, there is no freeze and sound works perfectly but when I
shutdown the computer, there is a message at the end of the shutdown process like :

[xxxxx.yyyyy] Power down.

Where x and y are some dynamic numbers (I think this is not always the same each
time I try to shutdown the computer).

But the computer stayed powered-on. If I add again the snd-hda-intel to the
hotplug blacklist file, the computer shut off correctly so I think this is
related to this dpatch.
