Hi,

>        %MAC_MOVE-SP-4-NOTIF: Host 00d0.009e.2400 in vlan 42 is flapping between port Po1 and port Gi1/7

ah yes - have you traced the path that these routes take - portchannel goes
to where, Gi1/7 goes where?  could they have introduced a loop locally 
at the edge - eg if portfast was enabled and they've managed to plug switch
into switch?
