We have also seen this with the 4.19 kernel in buster. Links to Ubuntu bug reports and commits (but I have not verified that these patches fix the issue): https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1836152 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1836177 commit 17fbc0334e61b81ae25213c220f80c666af3cfb0 Author: Kai-Heng Feng <kai.heng.f...@canonical.com> Date: Thu Jul 11 15:16:46 2019 +0800 UBUNTU: SAUCE: e1000e: disable force K1-off feature BugLink: https://bugs.launchpad.net/bugs/1836152 Forwardport from http://mails.dpdk.org/archives/dev/2016-November/050658.html MAC-PHY desync may occur causing misdetection of link up event. Disabling K1-off feature can work around the problem.
