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!
[    4.383543] [drm:amdgpu_device_init.cold [amdgpu]] *ERROR* sw_init of IP 
block <psp> failed -2
[    4.383668] amdgpu 0000:0a:00.0: amdgpu: amdgpu_device_ip_init failed
[    4.383672] amdgpu 0000:0a:00.0: amdgpu: Fatal error during GPU init
[    4.383688] amdgpu: probe of 0000:0a:00.0 failed with error -2
[    4.427485] random: fast init done

The host has a RADEON RX 6700 XT video card. 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.
