So this platform is a Xeon E7-8867. which makes it a broadwell based Xeon.= =20 I don't see it in the logs, what is the reported device ID? Those Xeon have the capability disable the route to the ICH, which is these quirks are mean= t to work with. It also looks like you are using an out of tree driver? Is that correct? Are you unable to use MSI with this device? Sean -- You may reply to this email to add a comment.
