Your motherboard wouldn’t happen to be an AsRock? There’s been reports of ASRock mobos in particular causing problems with 9000 series AMD chips, especially the X3D. Mate of mine running windows has been having it crash especially when idle at desktop.
I’m not familiar with a green Linux equivalent to the BSOD. Is it completely green? In that case it may be a graphics problem…
ZFS doesn’t have fsck because it already does the equivalent during import, reads and scrubs. Since it’s CoW and transaction based, it can rollback to a good state after power loss. So not only does it automatically check and fix things, it’s less likely to have a problem from power loss in the first place. I’ve used it on a home NAS for 10 years, survived many power outages without a UPS. Of course things can go terribly wrong and you end up with an unrecoverable dataset, and a UPS isn’t a bad idea for any computer if you want reliability.
Totally agree about mainline kernel inclusion, just makes everything easier and ZFS will always be a weird add-on in Linux.
Like Hawke said it seems like the graphics card or driver crashing. Very hard to troubleshoot, especially when it’s random. Bazzite probably already has very recent drivers, there’s this post on the bad website listing some things to try. This stuff can lead to superstitious thinking, with people changing something, rebooting to have it work fine for a while then they post that change as if it fixed it.
God speed.
