I opened a Service Request yesterday with Dell regarding my Lite-On CX2 NVMe Series drive. The workstation group escalated the support ticket to their "High Complexity or Ubuntu" group and told me they would get back to me by tomorrow (in 24-48 hours).
The last time this happened, there were 329 different errors on the root file system, all seemingly random. I included a couple of them in Comment #4 above. I think I've deleted the file that captured all of the errors. Even after recovering from the file system errors, it does seem that I lost some files, such as the icons in Thunderbird context menus and other random things. $ sudo nvme get-feature -f 0x0c -H /dev/nvme0 get-feature:0x0c (Autonomous Power State Transition), Current value: 00000000 Autonomous Power State Transition Enable (APSTE): Disabled Auto PST Entries .................
