sure, we have intel on-board controllers

07:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
        Subsystem: Intel Corporation Device 3584

        Capabilities: [e0] Vital Product Data

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
