Not sure if this is a current issue.
Some days ago I build a 10.2 system with an on-board em0 to test my new
assigned IPv6 (only) connectivity and seeing similar symptoms.
Haven't measured the time but the system stops forwarding packages on the em0
until I bring it down and up again (sometime additional restart pf)
