Redit tells me:
Critical Warning: 0x04
Turns out, that according to Page 122 of the NVMe Document , Byte 00,
bit 4 (0x04) of the Critical Warning means:
If set to ‘1’, then the volatile memory backup device has failed. This
field is only valid if the controller has a volatile memory backup solution.
