I have broken the link to duplication of bug #1124803 "NetworkManager doesn't respond to SIGTERM in daemon mode". This bug have been reported by Ernie and in the discussion of bug #1124803 he insists that his bug has not fixed.
Network manager 0.9.6.0 in 12.10 quantal is really affected by that bug, and if the patch mentioned there is applied system shuts down correctly. On 'stop network-manager' dhclient is stopped as well. If network-manager 0.9.8.0 from Raring is installed to 12.10 Quantal then dhclient for some reason (unclear for me) does not open lease file in /var/lib/NetworkManager so root filesystem can be cleanly remounted readonly. In Raring network-manager 0.9.8.0 opens a lease file in /var/lib/NetworkManager, but after 'stop network-manager' dhclient (intentionally?) remains alive. The PID of dhclient is mentioned in /run/sendsigs.omit.d/ so, if I guess correctly, dhclient is not stopped during shutdown and /etc/init.d/umountroot can not remount / readonly due to the lease file open for writing. Any volunteers to debug further? -- 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/1073433 Title: Ext4 corruption associated with shutdown of Ubuntu 12.10 Status in Upstart: Confirmed Status in “linux” package in Ubuntu: Incomplete Status in “network-manager” package in Ubuntu: Triaged Status in “upstart” package in Ubuntu: Confirmed Bug description: 1. Format and label a target Ext4 partion using Ubuntu 12.04 2. Install 64bit 12.10 OS using that target without reformatting it 3. Shut down 4. Boot an alternate copy of Ubuntu 5.

I used Acronis True Image Home 2013 to create an image of the newly installed 64-bit Ubuntu 12.10, so I can recreate the symptoms of Ext4 filesystem corruption 100% of the time by restoring from the image, booting, logging on and shutting down.
