Michael,

I see the same on a Ryzen 7 35750H APU + RX 560x Nitro5 Laptop.

reverting
https://github.com/freedesktop/xorg-xf86-video-amdgpu/commit/a2b32e72fdaff3007a79b84929997d8176c2d512

fixes the problem for me.

I tested kernels 5.2*, 5.3, and all have the same problem 
when suspending from X with that commit, without the commit
everything is working fine.


( will test 5.4git once drm-next is in but I tested amd-staging-drm-next
some days ago and that didn't work also )

If you need more informations please let me know.

I can test any kind patches kernel/X/mesa and/or give
you debug info if you tell me what you may need.

Best Regards,

Gabriel C
