Was running Ubuntu 20.04.4 and PhoenixMiner does support amdgpu-pro-21.30-1290604-ubuntu-20.04 and should work. Have you tried installing it like amdgpu-install --opencl=legacy,rocr --headless ?
As that should support the RX 580 as well as the RX 6600 (XT).
Make sure you uninstall the drivers first before installing again.
Hi, thanks for info. I tried installing 21.30 using amdgpu-pro-install --opencl=legacy,rocr --headless.
I read this on Phoenixminer 6.0c:

AMD Linux drivers 21.40.1 has finally removed the requirement of PCIe atomics but there are problems when you try to mix Polaris (RX4x0/5x0) cards and Vega or newer cards on the same rig.
So I started to doubt I will ever be able to mix rx580 and rx6600.
But if you confirm you managed, then I will try again, maybe with fresh ubuntu install.
