--- Comment #5 from lumetili at gmail.com ---
I swapped in another card of the same generation (HD 7750 -> R7 250), these
errors keep happening, though they might not even be noticeable before the
computer completely freezes eventually. Not even SysRq works, I have to reset
from power button.

This time there was another error included:
