[Bug 869635] Re: long delay at shutdown/reboot - network-manager doesn't close correctly

[Erie]

actually this is not a bug. I have found the solution to this problem.

You just need to make sure that you have safely removes or eject all the
removable drives (USB falsh disk, External Harddisk, etc) before
shutting down. Because linux still reads it.

Mouse and external CD/DVD room doesn't have problems.

This way the message ( linux name : xxx tty1 modemmanager(805): caught
signal (15)) won't show up at all.

So you don't need to edit conf, remove modemmanager or anything at all.

Bug description:
  I've noticed the shutdown and reboot in oneiric is slower than in
  natty. This is reproducible on different machines with fresh
  installations.

  Disabling plymouth and vt.handoff=7 I can see that some processes are not closed:
  * Asking all remaining processes to terminate... [OK]
  * Killing all remaining processes... [fail]

  Killing network-manager at runlevel6, after the dbus shutdown signal,
  makes the shutdown and restart really faster (I'd say 5/10sec on low
  end machines like netbooks)
