Default NetworkManager/WPA-problems (?)

My log is filling up with:

Aug 23 12:20:36 localhost NetworkManager: <info> (wlan0): supplicant
connection state change: 6 -> 7
Aug 23 12:20:38 localhost NetworkManager: <info> (wlan0): supplicant
connection state change: 7 -> 6
Aug 23 12:20:38 localhost NetworkManager: <info> (wlan0): supplicant
connection state change: 6 -> 7
Aug 23 12:20:40 localhost NetworkManager: <info> (wlan0): supplicant
connection state change: 7 -> 6


...and on it goes...

I.e. each second second the connection (WPA) goes from state 7 to 6 and
then back again. I have used Google etc. to find out what is going on
but have not found any usable information.


Is there anyone out there that might be able to shed some light on this
issue? I.e. what is going on, and how I can fix it?


Regards,
Lars

Answering my own message. By looking at the source code I get that state
6 is "GROUP_HANDSHAKE", and state 7 is "COMPLETED" (from
wpa_supplicant_state_txt() in wpa_supplicant.c). So for some reason a
handshake is initiated each second second. But why?


I forgot to mention before; this is a fully updated Fedora 9
installation on a Dell XPS M1330, with a Intel Corporation PRO/Wireless
4965 card using the iwl4965 kernel module, and an old 3Com 3CRWE454G72
access point set up to use WPA and a hidden SSID. Signal strength is
excellent and speed is 54 Mbps.


I have also noticed the following line from time to time in the logs, at
the moment I have no idea what this means...:
Aug 24 16:55:07 localhost kernel: iwl4965: index 255 not used in uCode
key table.


Any ideas on why this is happening?

Regards,
Lars
