wpasupplicant 2.1-0ubuntu7 from Ubuntu vivid.  From the syslog output,
it appears the wpa_supplicant output is reacting to the kernel event,
with nothing relevant preceding it:

Sorry, it didn't appear to have any effect; DEAUTH_LEAVING would still
occur every ~60 seconds.

I've looked through the log for relevant NetworkManager stuff, since
reason=3/locally-generated disconnections are often a result of NM's
association attempt timing out or moving to a new network.  In this
case, I cannot find any evidence of NetworkManager disconnecting
intentionally, it seems to come out of nowhere.
