                                ^^^^^^^

Our driver versions seem to differ. I have 5.11.5.30-1292797 rather than  
5.11.19.98-1290604. It has the following SHA-256 sum:

ef242adeaa84619cea4a51a2791553a7a7904448dde81159ee2128221efe8e50
amdgpu-pro-21.20-1292797-ubuntu-20.04.tar.xz

Back then, I got it from https://www.amd.com/en/support/professional- 
graphics/radeon-pro/radeon-pro-w5000-series/radeon-pro-w5500 under
"Radeon(TM) Pro Software for Enterprise on Ubuntu 20.04.2" and the download  
still seems to point to a file with the same SHA-256 sum.

It could be worth trying the exact same version that I used?

I used ./amdgpu-pro-install without additional arguments. It is a symlink  
to the same script but the script executes different code if invoked with  
the `-pro` inserted. Not sure if it will make a difference, though.

After successful installation with `./amdgpu-pro-install` I installed  
additional packages from the repository added by the `amdgpu-pro-install` in  
order to enable the OpenCL features.

Debian 11 Bullseye. Before writing this post, I was still on kernel
5.10.0-8-amd64, but I just upgraded and the DKMS compiled successfully for  
the new 5.10.0-9-amd64.

Differences between our systems seem to be as follows:

 - Minor version difference in proprietary drivers
 - I installed by using the symlink with `-pro` in its name

I might add that I have installed a bunch of firmware from non-free and am  
running ZFS on Linux as provided by non-free package `zfs-dkms`.
