Setup a Dell EMC 14G server R740xd server with NVDIMM-N, update BIOS & NVDIMM firmware to latest available to customers. 2. Install and boot to Ubuntu 18.04 3. Notice that no pmems are enumerated. 4. Try #ndctl create-namespace -> Failure with device or resource busy. Actual results: No pmems are enumerated, cannot create namespaces.
