You need to layout your spanning-tree topology and determine the root. From there, track down all switch connections, etc, it appears there is an issue with a switch connected of 1/2,2/2?

I would also suggest turning the logging level of spanning-tree to 6 (if not already done) to see if you get any additional log messages.
