Interesting, your setup seems to skip a whole bunch of steps .. starting with:
device state change: activated -> disconnected Will have a look at the source and see how that could get skipped. Anything odd about your system - did you configure your wired connection in n-m "by hand"? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1169614 Title: /etc/init.d/umountroot: "mount: / is busy" due to dhclient is not stopped Status in “network-manager” package in Ubuntu: Triaged Bug description: The result is "mount: / is busy" and root filesystem recovery during next boot. network-manager 0.9.8.0-0ubuntu3 in Raring neither stop dhclient in response to "stop network-manager" nor remove pid file from /run/sendsigs.omit.d/ So dhclient skipped by /etc/init.d/sendsigs and a lease file is open for writing in /var/lib/NetworkManager while /etc/init.d/umountroot is running. As a consequence root filesystem can not be cleanly remount readonly before poweroff. In default setup the problem is hidden by plymouth. The problem does not appear if network is disabled or the cable is unplugged before shutdown.
