https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193601 Bug ID: 193601 Summary: em0: link state changed to DOWN / UP Product: Base System Version: 10.0-STABLE Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: freebsd@opensauce.de I have FreeBSD 10.0-STABLE running on an Intel NUC and the network connection is being dropped every minute or so. I have seen similar issues related to earlier versions of FreeBSD, but none for 10.0 yet.

It has shown wonderful performance but it has always had networking issues, so I am not sure if something has been poorly configured or if the hardware is going bad on me. How could I trace the cause of the DOWN/UP state changes? Or, is there any way to entice causal messages with link state change messages? e.g.: "link state changed to DOWN because ..."
