https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231166 Bug ID: 231166 Summary: 11.1->11.2 Update brings em network link state flapping Product: Base System Version: 11.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: steven_nikkel@ertyu.org Immediately after doing an upgrade from 11.1-release to 11.2-release the network connection using em0 constantly goes up and down. It's driving an I= ntel 82574 card on PCI-E. I've tried rebooting, power cycling, using different cables, switch ports and a different switch with no change. Prior everything was stable for many moons in the same configuration. Switched to using the onboard Realtek in the system and that is also stable with the same cable/switch.
