This just happened again while the temperatures were hardly higher, so it doesn’t seem to be a temperature issue. Unfortunately, I didn’t get a kdump for this one.
Strange; I have the system76-power package from AUR installed, but system76-power.service doesn’t appear on the list when I run systemctl, and systemctl status system76-power.service complains about not finding it as I mentioned.

I’m using latest right now, but this problem has persisted for a few years, so I don’t think switching to LTS is likely to help.
While running memtest86+, I did find a memory error at address 0x9d4d48, so I added memmap=4K$0x0000009d4000 to the kernel command line to reserve the memory around that. Now I’ll have to see if that improves the situation.
Update (since I can’t edit my last post anymore): Doesn’t seem that this solved the problem, as I got another random reboot. I tried running memtest86+ again, but after 12 hours of testing, I didn’t find any errors. I’ll try the LTS kernel if this problem occurs again.
I had a similar problem. For me, eventually replacing the motherboard seems to have been the fix. Not saying you should jump to that. But search my post in this subforum in case it gives any insights. A frustrating problem for sure.
