      if the NIC is bridged, maybe the switch is shutting down a loop? I know my HP switch, by default, shuts down loops to save the network.

        Confirmed there is definitely an issue there with em NICs in a bridge. Lose and re-gain link on the NIC and you'll end up with non-stop cycling.

        In my test case, after doing that to one NIC, all the NICs in the bridge are cycling link. That the case for you as well?

        I'll look into it, though it might be early next week, several other things I have to get finished today.

          Added a second machine to my setup and confirmed that all NICs on the bridge cycle when I swap ports on one.

          It may be worth noting at this point that the reason why I'm on the 2.3 beta is because on 2.2.x, the realtek NIC disappears when the HP/Intel NIC is added to the machine. Seems like any previous fixes for the issue in this thread might be related to the issue with the missing realtek NIC.

            Hmmm I have similar problem with em nics but they are not in the bridge. When I unplug one (wan dhcp) web interface stops to respond and never come back.
            If I unplug pppoe, link never comes back in console I see something about watchdog resseting…
            I never had any issues with nics until now.
            Can this be related?

              No, this strictly affects bridges, please start your own thread describing what you're doing and seeing if you're still having issues after the change back in the other thread.

                  This should be fixed now.

                    Updated to 2.3.b.20160217.1500 and tested with one DHCP client. Looks good!  :D Thanks

                        @jwt:

                        patch was reverted.

                        I'm taking this to mean that I should hold off on updating until the patch/fix is reintroduced.

                          No, it was the change that introduced the problem that was reverted, and the problem that change fixed was fixed in a different way that doesn't trigger this problem. You're fine.
