Thanks for looking into this. The solid-state–memory device in question is
Samsung SSD 970 EVO 1TB, S/N:…, FW:2B2QEXE7, 1.00 TB. It's no longer sold on
samsung.com but still sold as new on amazon (ASIN B07CGJNLBB; the Web site says
it has been sold there since April 24, 2018). So yes, given the dates in
https://en.wikipedia.org/wiki/NVM_Express#Specifications
https://en.wikipedia.org/wiki/NVM_Express#Specifications, the drive might be
aware of the NVMe 1.2 or 1.3 specification but, again hypothetically, not 1.4
or even 2.0. I wouldn't know how to check this, and firmware upgrades seem
unavailable ( https://semiconductor.samsung.com/consumer-storage/support/tools/
http://semiconductor.samsung.com/consumer-storage/support/tools/ mentions the
same version 2B2QEXE7). Just in case this helps, the motherboard is Asus WS
C422 PRO/SE.
Here is some debugging data:

As you see, the output is slightly different from that in
https://github.com/linux-nvme/libnvme/issues/550
https://github.com/linux-nvme/libnvme/issues/550, and `nvme list` does not
increase error_count (or at least not directly). If there's anything else I can
help with, please let me know.
Gratefully,
