System spontaneously rebooting at random, can't find a cause
I posted this over on the Universal Blue forums, but I haven't gotten any replies to it, so I'm posting it here: https://universal-blue.discourse.group/t/having-my-bazzite-system-slow-down-then-spontaneously-reboot-at-random/7081
I’m having a regular issue of my Bazzite install suddenly slow down to a crawl and then reboot itself. I've had it happen in so many situations (idling on desktop, running desktop apps and even in the middle of a game), and I'm at my wit's end on how this is happening.
Running “journalctl | grep Error” gets me these lines around the time I get the restarts:

A quick search uncovered some Linux users having stability issues with Ryzen 5000 CPUs related to undervolting, and I was running one (via the AMD Curve Optimizer) when I first installed Bazzite on this system, but turning it off has not stopped the restarts from happening. I've also tinkered with the power plan in the KDE Settings menu but that seems to do nothing as well. This issue has persisted between all the Bazzite builds that have come out and I've upgraded to since I installed almost a month ago, so it's happened among a bunch of different kernels and Nvidia driver versions.
Can anybody help me figure out what's going on here?32 replies
