I noticed this issue on one of the two computers I upgraded from xenial to yakkety. Specifically the affected computer was an 2016 Dell XPS 13. They're both similarly configured ubuntu installations with Broadcom nics, so it's curious that this only affects one of them. I'm not sure what debug information would be helpful, but I'm happy to provide anything that would be useful.
