Why does my Kali Linux system suddenly restart at odd times?

Question

Why does my Kali Linux system suddenly restart at odd times?

My Kali Linux system suddenly rebooted at 19:05. It used to be rebooted at certain times.

Where does the problem come from? Why does this happen?

Answer 1

The fact that there are no log messages related to the imminent shutdown just before it happens suggests this could be a hardware-triggered reboot.

The cause might be an intermittent hardware fault, or something like a hardware/firmware emergency measure against overheating. Or if your power supply is old, it might be just barely capable of keeping up with the rapid changes of input current of a modern i9-9900K processor, and ther reboots might be caused by the PSU being unable to keep the voltages at the correct levels and removing the Power Good signal as a result. And whenever the Power Good signal is lost, the motherboard will trigger an immediate reset to avoid random faults and data corruption.

(Pairing a motherboard using a non-overclockable home/economy H310 chipset with an overclock-ready i9-9900K processor seems kind of a mismatched choice to me, but I guess if the system was built during the COVID chip shortage, you may have picked whatever was available?)

My suggestions:

Evaluate your power supply: if it’s older than the rest of the system, it might be at the end of its useful life, or unable to react to the rapidly changing power requirements of modern processors. If either seems likely, buy a new power supply. Otherwise, see if you can borrow a known good power supply and see if the problem repeats with that.
If replacing the power supply won’t remove the problem, it might be a problem with the motherboard.

If the shutdowns don’t happen under Windows, then it might be a firmware problem for which Windows "knows" a workaround but Linux doesn’t.

Is your system firmware ("BIOS" according to ASUS) up to date?

In Linux, run sudo dmidecode -s bios-version; in Windows, start a Command Prompt as an administrator and run wmic bios get smbiosbiosversion.

The most recent version is 2208, but version 1605 and several older versions before that are described only as "improve system stability", which just might be relevant to the issue.
