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. There are some other bugs that might be caused by this issue: Bug lp: #1073433 Ext4 corruption associated with shutdown of Ubuntu 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1169614/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
