To prevent the automatic load of the NVIDIA drivers upon system boot:
Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
blacklist mlx5_core
blacklist mlx5_ib
Set "ONBOOT=no" in the "/etc/infiniband/openib.conf" file.
If the modules exist in the initramfs file, they can automatically be loaded by the
kernel. To prevent this behavior, update the initramfs using the operating systems'
standard tools.
Note: The process of updating the initramfs will add the blacklists from step 1, and
will prevent the kernel from loading the modules automatically.
• The firmware of existing network adapter devices will be
updated if the following two conditions are fulfilled:
• The installation script is run in default mode; that
is, without the option '--without- fw-update'
• The firmware version of the adapter device is
older than the firmware version included with the
OFED ISO image
Note: If an adapter's Flash was originally
programmed with an Expansion ROM image, the
automatic firmware update will also burn an
Expansion ROM image.
• In case your machine has an unsupported network
adapter device, no firmware update will occur and the
error message below will be printed.
"The firmware for this device is not distributed inside
NVIDIA driver: 0000:01:00.0 (PSID: IBM2150110033)
