1. Please describe the problem:
ndctl create-namespace -v -r region0 -m fsdax -t pmem
libndctl: ndctl_pfn_enable: pfn0.0: failed to enable
  Error: namespace0.1: failed to enable

causes Kernel-Error:
nd_pmem pfn0.0: Conflicting mapping in same section
(see dmesg output file attached)

2. What is the Version-Release number of the kernel:

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at :

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
yes, it happens on every 'ndctl create-ns for region0' in my current configuration. Ther should be still 50 GB free in this region

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

6. Are you running any modules that not shipped with directly Fedora's kernel?:

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

 rpm -qa | grep ndctl
