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.
