It first starts with a couple if link downs/ups on one port and finally the link on that  port negiotates to 1GbE instead of 10GbE, which then breaks the LACP channel on my Cisco Nexus for this connection.

Was this an issue noticed only with r151018 and not with previous versions, or have you only tried this with 018?

By your description, I presume that the two ixgbe physical links will stay at 10Gb and not bounce down to 1Gb if not LACP'd together?
