That's from our internal repository, but it is based on a 3.3-rc4
wireless-testing tree.
I am using nmcli for setting up connection with the AP and found that
the connection is setup to be automatic. That is reason why the log
shows auth attempt during module unload. It does not happen on each test
run.
I will use debug suggestions from Stanislaw and try to get more information.
