Public bug reported:

There's a known issue in nvme-cli where the compiler optimizes out BAR
accesses into a single 64B read rather than 2 32-bits. This causes some
devices to hang and reboot the system. This bug was fixed in version
v1.14. The ubuntu supported version should be >= v1.14.

** Affects: nvme-cli (Ubuntu)
