The Nilolay's bug was related to bcmwl-kernel-source package, mine's too but we both had a stopping shutting down with the message "mount:/ is busy" on a laptop HP presario
First I removed network-manager 'cause of the message "dont get "www.networkmanager1" while sutting down. It didn't change
2 I saw that my wifi card was not detected, I removed bcmwl-kernel and installed b43-installer. After reboot i didnt get my wifi then I reinstalled bcmwl-kernel. "mount is busy" came back. I reinstalled network-manager
3 I've done what Nikolay said on the bug 1304532 and now it is Ok : no mount busy while shutting down and my wifi card is detected. I think I bad installed b43-installer
I think that this bug is related with bcmwl. It happend for me before 13.04 but before I didn't need wifi
