--- Comment #23 from vlad@ivanov.email --- I had the same problem with Ryzen 2400G on kernels 5.2, 5.3 and 5.4, but it would only be reproduced when X was running. If I stop X before going to sleep, wakeup would work. I managed to fix it by reverting the following commit in X driver: https://github.com/freedesktop/xorg-xf86-video-amdgpu/commit/a2b32e72fdaff30...
