I could compare dmesg output from 202102 and 202104 (blindly typing commands). Significant errors in 202104 are : [ 4.383429] amdgpu 0000:0a:00.0: Direct firmware load for amdgpu/ navy_flounder_sos.bin failed with error -2 [ 4.383431] amdgpu 0000:0a:00.0: amdgpu: failed to init sos firmware [ 4.383433] [drm:psp_sw_init [amdgpu]] *ERROR* Failed to load psp firmware!

It seems that the amdgpu module enforces the presence of this chip's firmware in 202104, but not in 202102. I guess the next install ISO would include navy_flounder* firmware and this should no more happen. For daily work, I did indeed copy navy_flounder* in the firmware directory following phoronix reading. At least, it's no longer a mystery. Regards.
