  May  2 23:52:29 jpt-ThinkPad-SL410 kernel: [ 2040.220779] wlan0:
  deauthenticating from ca:6c:87:ab:dc:2c by local choice (reason=3)

  And then continues to associate again with the AP, I have seen
  suggestions that power off for interface powermanagment was a working
  work around, but it does not work in my case. And the earlier bug
  report was closed with a resolved status.

  I did not have this issue before upgrading to 12.04 and the 12.04
  installation is a clean one, SSD was formated etc, before installing
  ie not an upgrade from 11.10.
