As I have a very similar problem and also commented on the original 
debian bug report 
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1005005), I will add 
some information here on another amd only laptop (renoir AMD Ryzen 7 
4800H with Radeon Graphics + Radeon RX 5500/5500M / Pro 5500M).

For me the suspend works once, but after the first resume (I do know 
know if it is in the suspend path or the resume path I see a RIP in the 
dmesg (see aditional info in debian bug))  and later suspend do not 
work: It only go to the kde login screen.

I was unable due to network connectivity to do a full bisect but tested 
with the patch I had on my laptop:

5.10.101 works, 5.10 from debian works
5.11 works
5.12 works
5.13 suspend works but when resuming the PC is dead I have to reboot
5.14 seems to work but looking at dmesg it is full of RIP messages at 
various places.
5.15.24 is a described 5.15 from debian is behaving identically
5.16 from debian is behaving identically.

>> Is this system S0i3 or regular S3?

For me it is real S3.

The proposed patch is intended for INTEl + intel gpu + amdgpu but I have 
dual amd GPU.
