Hi Martin, There's a potential fix for this upstream, in v5.3-rc1 mainline build (thus not in v5.2), which is also applied to bionic-proposed (4.15.0-60.67).
Could you please test whether the issue is resolved with bionic-proposed [1] ? If that doesn't help, further regression/bisect test steps will be needed. Thank you! [1] https://wiki.ubuntu.com/Testing/EnableProposed The mentioned potential fix is: commit d17ba0f616a08f597d9348c372d89b8c0405ccf3 Author: Konstantin Khlebnikov <khlebni...@yandex-team.ru> Date: Wed Apr 17 11:13:20 2019 +0300 e1000e: start network tx queue only when link is up Driver does not want to keep packets in Tx queue when link is lost. But present code only reset NIC to flush them, but does not prevent queuing new packets. Moreover reset sequence itself could generate new packets via netconsole and NIC falls into endless reset loop. This patch wakes Tx queue only when NIC is ready to send packets. This is proper fix for problem addressed by commit 0f9e980bf5ee ("e1000e: fix cyclic resets at link up with active tx").
