https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256175 Bug ID: 256175 Summary: Network interface sk0 is periodically switched DOWN, then UP without apparent reason, correlated with network activity Product: Base System Version: 13.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: yuri@freebsd.org My /var/log/messages file looks like this: May 26 12:06:34 yv kernel: sk0: link state changed to DOWN May 26 12:06:34 yv kernel: sk0: link state changed to UP May 26 12:06:44 yv kernel: sk0: link state changed to DOWN May 26 12:06:44 yv kernel: sk0: link state changed to UP May 26 12:07:34 yv kernel: sk0: link state changed to DOWN May 26 12:07:34 yv kernel: sk0: link state changed to UP May 26 12:07:44 yv kernel: sk0: link state changed to DOWN May 26 12:07:44 yv kernel: sk0: link state changed to UP May 26 12:08:24 yv kernel: sk0: link state changed to DOWN May 26 12:08:24 yv kernel: sk0: link state changed to UP May 26 12:08:34 yv kernel: sk0: link state changed to DOWN May 26 12:08:34 yv kernel: sk0: link state changed to UP May 26 12:09:34 yv kernel: sk0: link state changed to DOWN May 26 12:09:34 yv kernel: sk0: link state changed to UP May 26 12:09:54 yv kernel: sk0: link state changed to DOWN May 26 12:09:54 yv kernel: sk0: link state changed to UP May 26 12:10:24 yv kernel: sk0: link state changed to DOWN May 26 12:10:24 yv kernel: sk0: link state changed to UP May 26 12:12:14 yv kernel: sk0: link state changed to DOWN May 26 12:12:14 yv kernel: sk0: link state changed to UP May 26 12:12:24 yv kernel: sk0: link state changed to DOWN May 26 12:12:24 yv kernel: sk0: link state changed to UP May 26 12:12:34 yv kernel: sk0: link state changed to DOWN May 26 12:12:34 yv kernel: sk0: link state changed to UP May 26 12:12:54 yv kernel: sk0: link state changed to DOWN May 26 12:12:54 yv kernel: sk0: link state changed to UP May 26 12:13:54 yv kernel: sk0: link state changed to DOWN May 26 12:13:54 yv kernel: sk0: link state changed to UP May 26 12:14:14 yv kernel: sk0: link state changed to DOWN May 26 12:14:14 yv kernel: sk0: link state changed to UP May 26 12:14:24 yv kernel: sk0: link state changed to DOWN May 26 12:14:24 yv kernel: sk0: link state changed to UP May 26 12:14:34 yv kernel: sk0: link state changed to DOWN May 26 12:14:34 yv kernel: sk0: link state changed to UP May 26 12:15:04 yv kernel: sk0: link state changed to DOWN May 26 12:15:04 yv kernel: sk0: link state changed to UP This was happening in 12-STABLE, and now this happens in 13-STABLE. This happens more frequently when network activity is high.
