We need a way to better investigate whats going on. Are we using dhclient or how are we getting the IP?
Anyway, I feel to nail this down we need first make this reproducible. For that having a "(re-)connect to eth on ubuntu" test case in our enablement suite that we just run 10000 times for a test job without rebooting and see if it breaks might do it... Maybe someone from Ricardo's team or naresh/soumya (all three CCed) can help write a simple lava-test that does that and integrate that in our enablement testsuite for lava-test? Once we can force reproduction we have a better chance to nail this down and we can ensure that priority is there to fix this in kernel etc. Note: not saying this has to happen now, but we need to improve how we deal with rarely happen issues in a way that we nail them down. Otherwise we will never reach 99.999% health job success :).
