I’ve been watching this thread while getting increasingly irritated by my WD SN770’s propensity to flub a wake-from-s2-idle and cause the kernel to remount all my filesystems read-only.
Yesterday, irritation exceeded trepidation and encouraged by @Klaas successfully hacking on @not_a_feature’s script I decided to take the plunge. In case it matters:
$ uname -r
6.1.0-1027-oem
$ lsb_release -a
No LSB modules are available.
Distributor ID: Linuxmint
Description: Linux Mint 21.1
Release: 21.1
Codename: vera
My first attempt at running the script failed. The output gave me the clue I needed. Mint does not include the nvme-cli package and so the command-line tools were not available.
Suggestion: the script be modified to check this and bale early. Happy to submit a patch (not sure it warrats a pull request).
With nvme-cli installed the script ran and produced some unexpected and faintly troubling output.

I steeled myself for a bricked SSD and rebooted. Happily, everything seemed peachy (and continues to be so).

Perhaps one of you knowledgeable contributors could help NVMe newbies (like me) understand what ‘Multiple Update’ means in this context.
Thanks for making this available. I’ll report back if it didn’t fix my read-only filesystem problem.
