Today I' ve seen an improvement in Quantal: the workaround suggested at #13 resumed working after I got a kernel update from 3.5.0-22-generic to 3.5.0-23-generic.
Per Sandor' s suggestion, I have added to /etc/init two files that relieve me from the burden of manually disabling/enabling the network manager. These two files are shown below. $ cat /etc/init/hack1-for-nm-bug.conf description "Hack 1 to circumvent NetworkManager bug in Ubuntu 12.10" start on started gdm script /usr/bin/nmcli nm enable true end script $ cat /etc/init/hack2-for-nm-bug.conf description "Hack 2 to circumvent NetworkManager bug in Ubuntu 12.10" start on runlevel [016] script /usr/bin/nmcli nm enable false end script -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1073433 Title: Ext4 corruption associated with shutdown of Ubuntu 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/upstart/+bug/1073433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
