    mlx4_core : Missing UAR, aborting


      OS: Ubuntu 16.04.3 LTS


      $ lspci | grep Mellanox

      01:00.0 Ethernet controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro]


      $ mstflint -d 01:00.0 q

      Image type:        FS2
      FW Version:        2.42.5000

      I have installed all drivers, ran  '/etc/init.d/mlnx-en.d retstart' , got :

      Unloading NIC driver: [ OK ]

      Loading NIC driver:     [ OK ]


      BUT can't see mellanox interface (ifconfig -a)

      when I type now 'dmesg | grep mlx' , I get:

      [0.991278] mlx_compat: loading out-of-tree module taints kernel.
      [0.991286] mlx_compat: module verification failed: signature and/or required key missing - tainting kernel

      [0.992621] mlx4_core 0000:01:00.0: Missing UAR, aborting


      What is the problem here?


      P.S. I had no problem with this NIC on my computer, when used Ubuntu 14.04 LTS
