After the kernel update prior to linux-image-3.2.0-45-generic and still continuing after the update to linux-image-3.2.0-45-generic I occasionally get the following message at boot time: "recovery required on readonly filesystem" (of my root partition). So it seems that at shutdown time the root filesystem sometimes isn't cleanly unmounted after the second last update of the kernel package.

Confirm that issue accross ubuntu. Some times ago, most of the affected users and devs was blaming the network config, and it have been baked to stop cleanly now (at least it seems to).
But it makes no doubt that the system is still not unmounted cleanly: is it an udev/systemd race or else. The logs cant help to find something usefull right now; maybe its time to add some tests here too.
