Hello Dainius,
Thank you for posting your inquiry on the NVIDIA Networking Community.
Based on the information provided, unfortunately you are running a non-supported combination with OL8 and the kernel version you are running.
Based on the RN, we support the following combination:
- Oracle Linux8.2 /w kernel 5.4.17-2011.1.2.el8uek.x86_64
- Oracle Linux8.3 /w kernel 5.4.17-2011.7.4.el8uek.x86_64
When we look in our lab on a system installed with MLNX_OFED 5.4, we see that the proper module is loaded, it does not show a dummy module. See below output from one of our lab systems.
