failed to reconfigure namespace: No such device
2°) With 4.18.0-13 no active namespaces are seen which seems more
coherent for non initialized NVDIMM-N with labels but no namespace can
be created.
Both patches (kernel & ndctl) listed in the github issue below needs to
be applied in order to get them working properly. Tested against the
current hwe 4.18 kernel.
