Memory Region Failure ibv_reg_mr failed [error code: 14] about assise

This likely indicates that the memory you're trying to register is out-of-bounds.

Try setting your device size to a value lower than 8G using the change_dev_size.py script. After doing so, recompile LibFS/KernFS, and then rerun mkfs.sh.

You're correct, thank you very much for the suggestion and help!

Do you mind if I clarify why the problem occured? Assise's NVM region is 8GiB and from what I understand, the actual size of the emulated NVM is indeed 8GiB, as shown through ndctl list

{
  "dev":"namespace0.0",
  "mode":"fsdax",
  "map":"mem",
  "size":8589934592,
  "sector_size":512,
  "blockdev":"pmem0",
  "numa_node":0
}

I believe this is due to an alignment issue. I'll leave this open for now and will check later if there's a possible fix for this.
