Perhaps u have some ideas also for following problem:
I configured one device (AIR-BR1310G-E-K9-R) as root (IOS: c1310-k9w7-tar.124-10b.JA1)
and I configured one device (AIR-BR1310G-E-K9) as non-root (IOS: c1310-k9w7-tar.123-8.JA2
In this combination the bridge funktioning OK.
because the non-root does not have a external Antenne i configured a other device (also (AIR-BR1310G-E-K9-R) with the same IOS as non-root. Now the Radio also stay in reset state with the same configuration. First i thougth itw as the wrong IOS (as explained in some cisco article). Therefore i downgraded IOS on this one.
