Let me > know what info you'd need/patches tested for debugging this. Thanks very much for testing this. Can you collect the complete dmesg please? We need the information about the host bridge windows and the device that we assigned resources to, and the snippet you included doesn't have that. If you're able to boot Windows and collect an Everest report (http://lavalys.com), that would be a great bonus. The goal is to allocate things the same way Windows does, but obviously I failed somewhere. Bjorn
