Yea - I can't get DS3617xs to work properly either on bare metal with 1.02a2, but it is a driver thing - I was told that a new loader needs to be compiled to support the version of the firmware and all the drivers associated with it.
I am able to get 1.02a and 3615 to work just fine, but I need to add in a NIC to the box that is compatible with the build.
I'm just hanging tight for now to see what comes next.
