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.
Thanks
Running Debian bookworm/testing installed amdgpu-install_21.50.2.50002-1_all.deb enable repository in /etc/apt/sources.d/amdgpu-proprietary.list and used the following command in the terminal:
amdgpu-install --usecase=opencl --opencl=rocr,legacy after installing it might barf about amdgpu-dkms but you can ignore that
Both my RX 6600 XT and the RX 580 are supported as you can check with clinfo.

GPU1 sits in PCIe 16x slot 2 (RX 580)
GPU2 sits in PCIe 16x slot 1 (RX 6600 XT)
The RX 6600 XT I have tuned for best performance for this card.
Still tuning the RX 580 as it can do over 30 MH/s but it might also be the driver version not being optimal for this card.
Had better results when using driver amdgpu-pro-21.30-1290604-ubuntu-20.04.tar.xz with the RX 580
Total power at the wall around 280W
Mining is more like a hobby for me as I mine with the RX 6600XT when I am not gaming.
Hope this helps.
