          Hello,

           

          Looking at the Mellanox OFED 3.2 release notes, it is mentioned in the compatibility matrix that the ConnectX-EN cards is not tested against this driver build. As this is an older generation card I would advise to use a previous driver stack which was verified and tested against your HCA.
