The log shows the WPA-PSK handshake completed but you were then 
deauthenticated by your AP.  You need to look on your AP to find out why.

It's possible that WME is being negotiated and confusing the AP.  There 
are issues with sending QoS-encapsulated EAPOL frames to certain AP's. 
You can try disabling wme use with

ifconfig ath0 -wme

before starting wpa_supplicant.
