System details
AMD Ryzen 9 5900X (24) @ 4.95 GHz, NVIDIA GeForce RTX 3080 Lite Hash Rate
What's wrong?
When browsing media-heavy sties like X, I'll get random system lock ups, requiring a hard restart.
Mouse is still functional sometimes, sometimes not. Audio continues, but eventually also stops.
This issue has come and gone, most recently came back in the last point version I think.
There are seemingly related issues, but an important distinction is that this is a desktop with a Ryzen chip with no iGPU. The only GPU in the system is the RTX 3090.
It has been tricky finding the right combo of flags for brave and chromium to get things to work smoothly, or at all.
Here are some potentially relevant logs from journalctl
