Ouch, I wouldn't admit that I have switches reporting those messages
still facing a customer.  The messages you show are from a device
running CatOS.  CatOS went End-of-software-updates in 2009.  There may
still be support available for another few months.

No etherchannel involved.  Just reporting that a port stopped
forwarding in that bridge domain (went down), then came back up.
Nothing here to indicate one way or another that you have CE troubles.
