I installed a system with Oracle Linux 8.6 to install the official updates. After yum update I tried to compile and install the Mellanox OFED drivers.
After reboot the mlx5_core not loading, I see the following message in dmesg:

Did anyone faced with the same situation?
With OS reinstall and driver install before update I can solve the problem but for later updates it should be good to know what is the issue.
