Still not working on 5.1-rc1. Also tested 4.18, 4.19. 5.0.

I tried some debug, and as I can see, system freezes after
error = dpm_suspend(PMSG_FREEZE);
in hibernate.c

System is A10-9600p + R7 M440. With nomodeset or without amdgpu system
hibernates, but completely unusable. Same bug searched with AMD FX-9830P +
RX560, and AMD A10-8700P.
