Thanks Richard. Yes, I talked with Titan; they suggested trying the pcie-m.2 adapter. I will try them again.
I have not checked for bios updates. Not sure how to go about that (last time I did that it required an msdos floppy disc).
Haven't tried the SSDs in another device because I don't have one. But the fact that replacing the SSD causes it to work, where it wasn't working before, tells me they were damaged. I have at least once power off/on the workstation, and the bios did not find any ssd to boot from. So power cycle didn't fix it, but replace ssd did fix it.
I will try Titan again later today, but just looking for ideas.
Thanks,
Neal

After about 1 year it stopped working. I could ssh to it, and almost any command would return Input/Output error. Unfortunately journalctl gave input/output error so I can't see logs. cat /proc/partitions did not show any nvme device (the root device) on which the OS was installed.I replaced the SSD with a samsung 980 pro. Reinstalled fedora. It then worked a few weeks, then the exact same symptoms.I replaced the SSD with another samsung 980 pro, this time with heatsink. Reinstalled fedora. It worked a few weeks. Then same symptoms.Then I replaced with a 4th samsung 980 pro, but this time instead of using the M.2 socket I used a pcie-m.2 adapter (in case something was wrong with the m.2 socket). Also added a surge protector outlet for good measure. Reinstalled. Watched the smartctl. No errors. Temperature was always low.Now it's failed again, exactly same symptoms.Any ideas?I remember your other email about a month or so ago and thought it was really strange. Have you tried the drives in another system to confirm they're truly dead?I would check for BIOS updates just for good measure. Other than that, have you had any communication with Titan about it?Thanks,Richard
