Title:
  wireless doesn't associate after waking from suspend

Status in “bcmwl” package in Ubuntu:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  on a macbook pro retina, the wireless often doesn't work after waking
  from suspend.  sometimes combinations of unloading and reloading
  kernel modules and restarting network-manager works; other times i
  need to reboot before I can reconnect to the wireless.

  here's syslog after a network-manager restart during one of the times
  i needed to reboot.
