I think i found a cisco bug with AP FALLBACK. It appears the cisco 1220 access points after upgrade WILL NOT fallback to first, second or tertiary controllers. These puppys stayed connected to the first controller they join but the radios bounced every minute in an attempt to join the (first/primary) controller. I will sniff the ap tomorrow... Its only the 1220s all the other APs fallback fine...
Anyone else have this problem?
