Would appreciate it if you > could shed light on this aspect. The two AMD devices are connected to the [0000:16] and [0000:64] buses respectively both are Intel 09a2. I'm not sure if the whitelist code will handle this topology. You may need to make more substantial changes to handle it. If adding the device to the white list doesn't work you can try disabling the check. If that all works then we'll need to somehow add support for this topology. Logan
