I currently have a Reform with the A311D installed. I love it and I use it all the time, but the only thing keeping it from being a true daily driver is the lack of solid suspend/resume support. I know it works for some people but my system will not wake after I suspend it. This seems to be a known problem with how the clocks are configured.
It sounds like the RK3588 has much better Linux support. How is suspend resume working for that one? I will definitely order one if it means I can put my laptop to sleep.
