The system seems to reboot only once a day and apparently this behavior are not related to any program or anything like that. I already ran memtest for approximately 2 hours and I don't have any error, so I don't think this is a hardware problem. For more context, I'm using btrfs with snapper, not using any kind of hibernation (but I was using) and I'm using sway. Message before reboot: Jun 04 20:56:47 arch rtkit-daemon[911]: Supervising 6 threads of 4 processes of 1 users. message that brings me concern after reboot(but appears only one time and not everytime my pc reboot)

when I was writing this, my system rebooted again, so two reboots today 🤡 and this time with a system freeze, I needed to force-shutdown with the case button

It could also be an abnormal CPU voltage.

Is there any reason why this message appears only sometimes? My system rebooted randomly like 6-7 times already and this message only appeared 2 times.

#

And there's anything that I can do to check if the problem is with my CPU. I already ran memtest86+ and I read that this indirectly tests CPU too.

I think only your vendor can do that.
