[Bug 113095] Re: On shutdown, NetworkManager shuts down before NFS unmounts, causing a long hang

[cotillion]

this problem is still present on my machine (12.04) since I can
remember. Shutdown happens always fast. Only if I mounted nfs-devices
the shutdown progress hangs after stating that "killing all processes
failed".

As the patches talked about in this thread are quite old (2009), I do
not want to install them to my system.

Standing by for further testing if needed.

Title:
  On shutdown, NetworkManager shuts down before NFS unmounts, causing a
  long hang

Status in “dbus” package in Ubuntu:
  Invalid
Status in “network-manager” package in Ubuntu:
  Incomplete

Bug description:
  I use NFS and NIS to connect some workstations to a server and /home
  is mounted with NFS from the server. The the system shuts down NFS and
  NIS cant connect to the server and do a correct shutdown because
  NetworkManager shuts down all network connections earlier in the
  proces. This results in NFS and NIS doing long timeouts and the
  shutdown or restart process takes about 10-15 minutes.
