nvme drive disappears after about an hour of uptime
I happened upon this thread, because I also bought and installed the Intel 660p 2TB. I've updated the wiki's "Pinebook Pro Hardware Accessory Compatibility" for its power states, and added some additional info on the discussion page.

I've also experienced the aforementioned disappearing, and it appears to happen under sustained, heavy IO. This even happens after ensuring power state 2 (2.6W max), changing the DTB to revert Max-link-speed from 2 to 1, and ensuring the barrel power cord was charging. Under some circumstance (unsure which), the lspci -vv command also returns no entries, but this does not always happen.

My operation was using Restic to restore from a USB HDD restic backup to the NVMe storage. I restored a limited subset of files to test and succeeded in copying; however, when I attempt to restore the full repo (about 650GiB, expanded to about 750GiB across about 150k files), the device disappears after a few hours. During this time, the battery level went up and down a bit around 80% charge, and slowly drained to about 50%, all while connected to mains power.

Rebooting and recharging do not seem to fix the problem. I've only been able to get it to show again by leaving it overnight, lending more credibility to the temperature theory.

I'm open to additional suggestions. Wanted to post this as a confirmation of trying the max-link-speed suggestion, and also see if anyone else has any further ideas.
