Some months ago i started having issues on my fedora installation. It began in 42, didn’t fix itself after updating to 43 and updating the bios to latest.
Basically, regardless of what i’m doing, after a variable amount of boot time (always over ~30 mins) the system goes through a complete hang without any particular sign of it happening. Audio starts looping the last ~.5 seconds the system was playing, and it doesnt show anything in the journal logs, even after leaving the frozen machine turned on for hours.
I have a ryzen 7 9700X, a radeon rx 6800 32gb over two sticks of ddr5 and was previously on a partitioned SSD. I bought a new one thinking the issue was Windows making a mess in the partition it couldn’t access but i had the same issue on the first boot of a fresh istance of f43 KDE plasma edition on a fresh drive completely dedicated to linux.
Only clue i have as of now is that i’m running my pc, monitor, sim steering wheel and nanoleaf lights all on a single plug cause it’s all i have in my room, but i never had system hangs on windows so either linux handles voltage drops differently or its a different issue. If you need any extra info i’ll provide them but having no dumps happen after the hang makes it way harder to identify issues. I tried keeping btop open while using the system and didn´t see any particular issue regarding temps, components usage or disk usage
