Comment 4 for bug 1061639

I can confirm that the unmounting issues are indeed fixed, and no more fsck warnings are shown in dmesg, but shutting down Quantal still takes conciderably longer than shutting down Precise.

Before this update, I could run 'sudo service networking stop', which would speed up the shutdown process a lot (which caused me to believe it was somehow related to network-manager), but since this update, stopping the networking service also seems to disable ConsoleKit, which will require me to enter my password in order to shut down; and the speed increase also seems to be gone.

Anyway, there is still something out there that causes Quantal to hang for a few seconds during shutdown, that might be somehow related to this.
