I see this is an old thread, but posting response anyway. Note the BSSID's recorded in the log messages. After failing dot1x on f9:e1, client is flipping over to a different SSID (f9:e0).

Best guess is that this second SSID is OPEN, no dot1x profile attached. So controller ignores EAPOL on that SSID and posts this message.
