So recently I have replaced my aging ROG Maximus XI Extreme Z390 motherboard with the new ROG Maximus Z690 Extreme, but the system suspend doesn't work and I'm slowly coming to realization that could be because the driver is not yet upstreamed into the kernel. It's annoying, because the old motherboard worked fine out of the box and everything else is fine with the new one, except the suspend.
Any ideas, suggestions?
