Hi Alex, I've managed to get a little further. I am currently running mainline (5.0.0-rc1) and am getting the errors below. Looking at the datasheet for the LS1012A, it mentions in the PCI Express section that: The PCI Express controller as instantiated on this chip does not support hardware coherency. All incoming PCI Express transactions are made non IO-coherent. Would AMDGPU still work with that PCI Express controller, or is this a show-stopper?
