  NetworkManager/wicd hang, might be driver  issue

Bug description:
  Recently I had issues with NetworkManager. When I try to restart or close
  NetworkManager, the process hangs. First it sends a SIGTERM to the
  NetworkManager process, and after a while it sends SIGKILL, yet nothing
  happens. After the attempt to restart/close NetworkManager, the OS behaves
  badly:
  - journalctl doesn't work, doesn't output anything, SIGTERMing/SIGABRTing/
  SIGKILLing it causes the kill command to hang (no matter how many times I try
  it), it also hangs the terminal
  - 'sudo dmesg' hangs (killing it with SIGKILL/SIGTERM/SIGABRT hangs the kill
  command, can't close the terminal)
  - the OS won't reboot/suspend/shutdown (it does only after holding the restart
  button)

  Suspending/rebooting normally/shutdowning normally the laptop hangs the OS
  (because of NetworkManager).

  What I've tried:
  - reinstalling NetworkManager (uninstalling it using --purge, installing it clean)
  - deleting ~/.config
  - deleting ~/.cache
  - installing a version from NetworkManager from Debian (version: 1.8.4.2),
  reinstalling NetworkManager from Ubuntu back
