Yes, I have and it works fine in the mode Bull is using. We did have
some interoperability problems between ConnectX and mthca, but
those were back in May, and fixed by Roland a short time later.

In any case, the Bull kernel log message indicates NFS/RDMA has
connected successfully, so I believe the problem lies elsewhere.
