I would resend your question to linux-rdma at vger.kernel.org, it's much
more likely to be a driver issue than a packaging problem.
With that said, in the cases where ib1 doesn't come up, I would do:
grep . /sys/class/infiniband/mlx4*/ports/*/link_layer
(I'm assuming you only have one ConnectX adapter in the system), and see
if the output looks like
/sys/class/infiniband/mlx4_0/ports/1/link_layer:InfiniBand
/sys/class/infiniband/mlx4_0/ports/2/link_layer:InfiniBand
I've seen cases where one port gets mis-negotiated as Ethernet.
