Alexander, I tried to reproduce the regression on Dockstar with 3.14.0 and 3.14.0-07247-gcd6362be, netconsole enabled, DHCP (dhclient). I can neither reproduce any issues with ethernet before nor after dhclient kicks in. I can also use netconsole just fine and see plenty of kernel bootlog messages sent to netconsole receiver. Can you _please_ share a full report how to properly reproduce it? Sebastian
