    sure, we have intel on-board controllers

    07:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)

    the cable issue I have to verify ...

    the odd thing about this behaviour is, that there are several kvm
    virtual machines running on this box as well, and even when omnios
    goes 'offline' the kvm hosts (talking over the same physical
    interface) are still reachable. They themselfs can not talk to
    omnios either ...

    cheers
