My computer reboots some time (could be 0 minutes, could be 2 hours) into playing a steam game.
These are always the last few line of the journal prior to the reboot:

Nov 25 21:36:53 My-Desktop org_kde_powerdevil[785]: powerdevil: Can't contact ckThis is a known issue with steam, but not to the point of crashing the system:
https://github.com/ValveSoftware/steam- … ssues/5607
Could this be related to the sudden reboots?
I tried stress testing the system in various ways outside of steam (unigine, memtest, gputest) and could not reproduce the reboots.
Any ideas on how to verify and/or solve the issue?
