madwifi_process_wpa_ie: Failed to get WPA/RSN IE

It looks like the error comes from :
        ......
        ioctl[IEEE80211_IOCTL_SETMLME]: Argument list too long
        madwifi_set_sta_authorized: Failed to unauthorize STA
00:92:c3:80:05:7d
        ath0: STA 00:92:c3:80:05:7d IEEE 802.1X: unauthorizing port
        Could not set station 00:92:c3:80:05:7d flags for kernel driver
(errno=29).
        ......

I don?t know why it failed to unauthorized?my password is OK?

And the message said it could not set station flags for kernel driver?is it
lack of something in my kernel ?
