I'm pretty sure that the problem is because the network stops before filesystem unmounts, and so the nfs unmount hangs because the file server is unreachable.
The fix would be to unmount network file systems before stopping the network. But that would require stopping processes that use network file systems even sooner than that. But some processes are used to manage the network card (particularly wireless network) so they can't be killed before un-mounting the network file systems. The current workaround is to use windows with roaming profile or something like that, I believe that works quite well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/614731 Title: shutdown hangs with wlan autofs/nfs mounted homedirs -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
