Thanks for trying this out.

Yes, as I mentioned the remote end is not responding to SMA packets (as
the right modules appear to be loaded to do that). I don't know why this
is but this is NOT an OpenSM issue.

Right, OpenSM sees the Physical Link Up and tries to bring the port to
active but can't because the remote SMA is not responding. Periodically,
it downs the port and reattempts to bring it back up (but can't).

Right; that's the same thing the SM sees. The remote SMA is not
responding to requests (same request SM Get NodeInfo).

Can you turn on madeye on the remote node and see what packets are
received and sent ? Let me know if you need help with that. I think you
said you were running OFED, right ?
