The Samsung PM9B1 512G SSD found in some Lenovo Yoga 7 14ARB7 laptop units

nvme nvme0: identifiers changed for nsid 1

What EUI did it report before? Is the identifier stable after
multiple resume cycles?

Can some of the Samsung folks here reach out to the relevant firmware
team to see if they have any clues?

I will check.

Took more time than I wanted. Firmware team mentioned that issue existed
in this firmware. This is fixed in new firmware, but bit of travel time
is involved when official release from OEM (Lenovo) comes out.

Hope the information is sufficient, and quirk can go in.
