Description (partial)

We see when a downstream interface is flapped on 3560GC

%EC-5-CANNOT_BUNDLE2: Gi4/3 is not compatible with Gi4/4 and will be suspended (Operational flow control send of Gi4/3 is off, Gi4/4 is on) 

We should not trigger this as the initial port-channel state shows as send flow control off.

This does not happen on a 3750X
