i had this problem too.
my status: - dont have network manager installed. - /etc/network/interfaces doesnt have an auto wlan0 entry - im not applying the fix everyones using here (adding to alsa-utils the ifdown command)
the problem has gone away.
one thing i may add. this might be related to this bug: https://bugs.launchpad.net/ubuntu/+source/netbase/+bug/290230 since the moment i removed all configured networks, computer started shutting down correctly...
