And at last it has been fixed in 4.14-rc3 by commit 820608548737
("drm/radeon: disable hard reset in hibernate for APUs"), although there
is the problem that the screen is blank after resume from hibernation.
But a suspend/resume cycle brings it back, I can live with that. 

Patch is attached for your convenience, it should appear in the stable
kernels soon.

Cheers,
