Same thing here!!! Getting rid of the smart switch apparently solved the issue and no more shutdowns! 4 days without any issues, which is a record! Strange that there was another PC on the same smart switch (mostly on standby) that didn't get impacted with any shutdowns... probably the load around 30-40W triggers the issue... Thanks for helping sorting out the issue, I would take a while to get there.

Here the power runs through a smart switch which measures the energy usage, just got rid of that, let's see. In my case the computer completely turns off, that's pretty interesting, it's not a simple crash or reboot. Hopefully it's the plug, otherwise I will start from the scratch.

Fair enough, it was out of desperation that I tried to upgrade, hoping something in the kernel or similar fixed my issue.

Good point, but it's completely the same PSU a Corsair RM750X, only difference being the year, one being the 2018 version and the other the 2021 or similar (simply swapped PSU's with the gaming PC). I can definitely try to swap the cables, if the issue continues, but I think I will start from the scratch with a clean installation. it's possible that the situation started when I swapped from macvlan to ipvlan, as recommended, but apparently I can't change it back to macvlan on unraid 7.

I don't want to discourage you, but In my case I swapped a modular PSU (kept the old cables) and the random reboots are still happening. Nothing in syslog. Last night it was at 3am after 3 days running without any issues. Here follows the list of Docker images I run, do you see anything familiar? Most are now disabled to try to sort out the issue.

Any update here? Also going crazy as I have exactly the same issue. I bough an entire new PC trying to sort it out (it was due to be honest) and even with a completely new setup (only 4 disks and PSU cables remain from the old setup). Every 24 to 48h the computer "reboots" alone and is waiting for the password to start the array. Nothing in syslog. Just tried to disable some power efficiency optimizations I added a few months ago, but in my case it must be software related, since everything is new hardware

Nice improvement on my case. Thanks a lot!
