I don't see the local deauth request, but I do see the following when it 
fails for me:

WPA: Key negotiation completed with 00:19:e3:fa:b7:f2 [PTK=CCMP GTK=CCMP]
Cancelling scan request
Cancelling authentication timeout
State: GROUP_HANDSHAKE -> COMPLETED
CTRL-EVENT-CONNECTED - Connection to 00:00:00:00:00:00 completed 
(reauth) [id=0 id_str=]
EAPOL: External notification - portValid=1
EAPOL: External notification - EAP success=1

Notice the invalid bssid. This is with wpi(4).
