on top of that):

TO FIX THE ISSUE'S FIX
-----
TODO: FEEDBACK ABOUT PROPOSED USERLAND FIX
and the userland fix was, indeed, the ndctl patch I did a SRU for.
UNFORTUNATELY I can't reproduce the issue with QEMU. I have tried
different label sizes in multiple attempts and wasn't able to cause the
labeling error (making sure it was fixed). With that it is hard for me
to guarantee the fix is good and I'll depend on a feedback from
reporter.
There is a PPA in comment #19 containing the fix. I'll flag this case as
incomplete while I have no feedback, as we wouldn't be able to verify
the fix in order for it to land -updates archive.
Nevertheless, documentation here might be important to others, in order
to understand the errors.

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.
