I have same issue with Macbook 4,1 (Early 2008).

I noticed same symptom as Martin (activated -> unmanaged after resume)
and looking network manager code (do_sleep_wake() in nm-manager.c) it
seems to be related to wake on lan stuff.

So, I modified nm_platform_link_get_wake_on_lan() to always return FALSE
for wifi and with that change wifi is resumed after sleep.

Timing change is probably just hiding the real bug, so this is more of
an ugly hack than proper workaround.

Title:
  NetworkManager failed to function after suspend and resume

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  NetworkManager failed to function after resuming from suspend. The
  indicator applet in the Mac OS style menu bar showed the empty
  quarter-circle, and clicking "Enable Networking" didn't change the
  menu options or the style of the applet. Running "sudo service
  network-manager restart" brought back functionality.

  $ dpkg -l systemd* logind*
