I believe Tai-hwa Liang has a fix for this pending re approval.  You're 
seeing beacon misses on the client but when the client scans to 
reassociate it bogusly creates a new entry in the scan cache and things 
get confused.  If his commit doesn't fix your problem check on the ap 
side to see if there are auth+associate requests coming in when you get 
a beacon miss on the client.
