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. https://github.com/pmem/ndctl/issues/78 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1811785/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
