Try turning TSO off.. i.e. ifconfig igb3 -tso or sysctl net.inet.tcp.tso=0 The transition to iflib has exposed much jankiness in the Intel "shared code" of the e1000 drivers. In particular, the locking contracts may not align with FreeBSD locking primitives. I have boxes running the legacy driver that are clearly reliant on the watchdog reset for steady state which is unacceptable. We are actively looking into this at LLNW, but additional reports and help are appreciated.
