Is my machine dying?

Thank you for the report. I have just checked my own dmesg O/P and seen that error message twice - as in your attachment. The links you gave above are useful, and show that the problem is not Mageia specific. Indeed, the only bad effect is that of rotating journals unnecessarily. The upstream bug report: https://github.com/systemd/systemd/issues/28250 > Is my machine dying? Almost certainly not.. Unsure what to do with this. Leave it open until upstream fixes it? Close wontfix (= cannot fix)? CC'ing tmb for his opinion.

It can also happen if the system is set to use utc, but the clock in the hardware is set to local time, or vice-versa. Some real time clocks run too fast when the system is powered off too.

Ping Thomas.
If the system is using ntp, the in /etc/sysconfig/ntpdate add the option SYNC_HWCLOCK=yes If using chrony, ensure the option rtcsync is not commented out in /etc/chrony.conf That way the real time clock will be synced with the cpu system clock every boot. If the message Monotonic clock jumped backwards still shows up every boot, it indicates the real time clock is running faster than it should be, or is somehow getting changed by another os such as windows. Windows keeps the rtc set to local time by default. With linux you choose during install. If dual booting with windows, see https://superuser.com/questions/975717/does-windows-10-support-utc-as-bios-time Make sure /etc/sysconfig/clock is set correctly. I have UTC=true in my system.
