I am able to reproduce this error with a PM173X.

nvme id-ns:
root@missingno:~# nvme id-ns -n 1 /dev/nvme1 | grep eui64
eui64 : 00253891010005b3
root@missingno:~# nvme id-ns -n 2 /dev/nvme1 | grep eui64
eui64 : 00253891010005b3
root@missingno:~# nvme id-ns -n 3 /dev/nvme1 | grep eui64
eui64 : 00253891010005b3

I will report this to our firmware team. Meanwhile, Could you paste your
output id-ctrl output here? I am interested in the fw version you are using.
