That is normal. EAPOL state machines force the port to be unauthorized
before .1X authentication has been completed.

and here the port is authorized..

I don't know what that is, but it looks like a corrupted frame.

Did you get these log items immediately after the authorizing message or
was there a delay of about 5 mins here? This looks like normal
disassociation of a station after inactivity timeout. You should be able
to get more information be adding debugging verbosity with '-d' command
line option.

http://hostap.epitest.fi/ has a link for downloading CVS snapshot.
Please note that the configuration of hostapd has changed. In the CVS
version, hostapd uses a configuration file instead of command line
