I have an AMD machine and I am using connectX-4 cards. Though they are showing up in lspci and even when my installation of OFED (MLNX_OFED_LINUX-4.6-1.0.1.1-ubuntu14.04-x86_64, tried 4.2 as well) gets successfull.
/etc/init.d/openibd restart shows following output
Many thanks for posting your issue on the Mellanox Community.
Based on the information provided, I did a quick test in our lab, because the kernel you are using is not the default kernel which comes with Ubuntu 14.04.5 (comes with 4.4.0-31-generic).
Based on your kernel version, I was able to successfully install the driver and had no issues when starting the driver.

We recommend to do a full uninstall of the driver and reinstall the driver, make sure that also the header DEB is installed for this kernel.
If after the installation, you are experiencing the same issue, then we would recommend to look into your BIOS settings as it involves BAR assignment on the PCIe bus.
