Is it supposed to work? Now if I use that option, monitor powers off (no signal) when it's initializing amdgpu and I have to reset the computer. Instead of crashing, could it not just give an error or something? I have Asrock X370 Taichi and Sapphire RX550. With mem_encrypt=off it works OK: [ 8.012120] [drm] initializing kernel modesetting (POLARIS12 0x1002:0x699F 0x1DA2:0xE367 0xC7).
