Blender Cycles on Linux does not work with an AMD GPU. Updating either the kernel or ROCm has a 50-50 chance of completely breaking Cycles. By comparison, I had zero issues with Cycles, either CUDA or OptiX, on my 2060. OptiX is also a better denoiser that runs on the GPU, while AMD only has OpenImage that runs on the CPU (GPU support is questionable at this point).

That sucks, but that doesn’t mean that it doesn’t work. I’m on Debian stable and it works fine for me, except for weird crashes from time to time.
