Title:
  Very slow restart/shutdown time at random (but very often)

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  When trying to restart, very often the time for shutting down the
  system goes beyond 10-15 seconds and more. I have tried to go to the
  menu and press restart again (some seconds after the first pressing),
  the system restarts immediately. That happens with no pattern
  occurring.

  The only reproducible case is only when I try restarting soon after
  booting (after all programs seem to be loaded), a window prompting for
  entering the login keyring password appears and the system does not
  restart until the password is entered.

  I have tried several times to reboot from terminal, but the problem
  did not appear. However, it might be because of the seemingly random
  nature of the event, since I could not find any pattern for its
  occurring.

  I have tried to restart after disabling networks couple of times and
  it restarted on time. However, it needs to be tested more. I have
  looked at this issue:
  https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1061639 , but
  it does not provide any solution to my problem. I suspect it might be
  network-manager related because of the discussion there.

  I am using Samsung Series 9 NP900X4C-A04US, Ubuntu 12.10 amd64. I have
  tried the kernel 3.8-rc1 and the bug appears again. Therefore I have
  marked it as kernel-bug-exists-upstream.
