The symptom of this issue is FCS error counters incrementing on control plane system controller peer HG links.
Error counters increment, no system impact is observed aside from the counters incrementing.
Run a system with 1.8.1+ that has the 6.5.26 version of the broadcom SDK.

Had to modify SDK at init time to properly set advertisements to disable FEC on the peer links when running 6.5.26 SDK.
