I had a ROG Zephyrus G14 "AMD Advantage" laptop with a AMD GPU in it that suffered from these "ring" crashes (according to dmesg). They came and went every few months sometimes with several weeks between crashes. When it would happen, audio kept playing but the display was frozen (can't even go to tty) and I had to force poweroff. The crash could also happen on Windows (I installed it just to test repro) but Windows handled restarting the GPU so it wouldn't freeze unlike Linux. The conclusion, at least in the community of people with that laptop, is that it was a hardware defect and the laptop needed to be RMA'd. ASUS wouldn't do anything for mine though despite explaining the issue to them and showing it happening on Windows.

Either way, I now own a Framework 16 with a 7000 series GPU and am very happy :)
