Onboard NIC hanging

I have an Intel i7-4790k on an Asrock Z97 Extreme6 motherboard, which has dual gigabit LAN ports, one with a Realtek chipset, the other an Intel chipset, and I have rules to name them accordingly, for simplicity's sake.  eth-realtek connects directly to the Internet (no router) and Network Manager is tasked with sharing the connection via eth-intel.

I've been watching my system journal as of late, as a result of kernel lockups (hoping to see some useful message right as it locks up), and I managed to catch this.  It didn't result in a kernel lockup, but I don't like what it says.

Is this something I should be concerned about?
