Thanks for tips! I have followed those instructions and it did not help:

$ cat /etc/depmod.d/nvdimm-extra
override nfit * extra
override device_dax * extra
override dax_pmem * extra
override dax_pmem_core * extra
override dax_pmem_compat * extra
override libnvdimm * extra
override nd_blk * extra
override nd_btt * extra
override nd_e820 * extra
override nd_pmem * extra

As you can see 'ndctl' also cannot load the extra test version of the modules even if there is the following file:

$ cat /etc/depmod.d/nvdimm-extra
override nfit * extra
override device_dax * extra
override dax_pmem * extra
override dax_pmem_core * extra
override dax_pmem_compat * extra
override libnvdimm * extra
override nd_blk * extra
override nd_btt * extra
override nd_e820 * extra
override nd_pmem * extra

Can I try anything else? Do you have any suggestions?
