Comment 13 for bug 119308

I don't know if this is related but I had a shutdown issue with feisty and gutsy, it was module snd-hda-intel that would hang. (black screen no info) So what I did was went to the script for the actual halt command in /etc/init.d opend the halt script and at the top of it added rmmod snd-hda-int so it unloads that modual at the start of shutdown. Works a charm.
