Forum Post: Wifi crash when two systems with same SSID are powered up : WARNING: at net/mac80211/sta_info.c:450 sta_info_insert_check+0x7c/0x90 [mac80211]()

I get a stream of errors like this below on my AM3352 WL1271 system if I power up one system while another is powered by the same SSID.  Although I can avoid this by ensuring all systems have unique SSIDs, I'd prefer to get the problem fixed, as we usually clone our Flash cards from a common image.  How can this be fixed?
