Ubuntu 20.04.2 - MLNX_OFED installation troubles


I am pretty new at this and trying to install mlnx_ofed for a small scale application involving:

3 HPz840 workstations with Mellanox ConnectX-3 VPI MCX354A-FCBT cards (Firmware version: 2.42.5000) connected together with a Mellanox SX6005 unmanaged switch.

I got 5.11.0-43-generic 20.04.2-Ubuntu installed on all 3 machines.

I have downloaded MLNX_OFED_LINUX-4.9- which seems to be the correct driver for my ConnectX-3 cards.

The trouble is this driver seem to be supporting kernel 5.4.0-26-generic.

What are my options other than downgrading the kernel?

I attached the installation log (mlnx-ofed-kernel-dkms.debinstall.log)

I have also tried:

sudo ./mlnxofedinstall --without-dkms --add-kernel-support --kernel 5.11.0-43-generic --without-fw-update --force

Failed to build MLNX_OFED_LINUX for 5.11.0-43-generic

attached the log of this attempt as well: mlnx_ofed_iso.38990

Any help would be appreciated

Hello Onur,

Thank you for posting your inquiry on the NVIDIA Networking Community.

Based on the information provided, the kernel version you are running is a HWE (Hardware Enabled) kernel, which unfortunately we do not support.

The kernel which is supported with this release is 5.4.0-26-generic.

Thank you and regards,
