FreeBSD version is 11.0-RELEASE-p1. It is a server machine: The CPU is Xeon E3-1275v6. The motherboard is Intel DBS1200SPLR, it has two Ethernet ports, both using igb driver. I tried wiri= ng each and the panic occurs either way, but only if dhclient is run on the ac= tive (plugged in) interface. I attach the crash dump from one of the panics.
