System frequently crashing after GPU drivers update

For me, mesa 21.1.4 finally fixes the problem! For everybody who is interested in testing it:

  1. sudo pacman -Syu
  2. sudo pacman -S yay
  3. yay -S downgrade
  4. sudo downgrade --ala-only mesa
  5. Select option 102 for mesa 21.1.4
  6. Reboot to apply changes.

Thanks to the mesa, firmware, linux kernel, and manjaro developers! Maybe we can support them by donating a coffee?
