It seems, that problem has been solved when i try to disable CPU C states and extended C states in bios in my case. It's about one month without freeze. May be that it's relates to CPU C states VS power supply, which has problems with lowered power consumption or simly doesn't support this feature correctly.

It never happens while I am using the PC, only when I am away. It sometimes runs through a whole night, and sometimes it freezes when I leave it idle for just an hour or so. Once it froze while the screen was not blank yet, same situation. I have tried to disable power management in KDE and run without external screen and external harddisks, just on battery with nothing connected, then it also happens. The screen is usually blank, there is no reaction to either mouse or keyboard, switching to a console not possible, connection through VNC or SSD not possible. I need to hard-shutdown by long-pressing the power button. There is nothing in dmesg or syslog, it just ends and continues with the restarts. No kernel panics or something like that. Any advice on how to trace down the issue or similar experience?
