Did you test them independently or just together? setting dpm=0 is irrelevant if acpi=off since there will be no resource restrictions. You need to test them independently. > > I've been working with another user that has the exact same system (XPS > 9575) and an RX 580 and is having the same issues.

PCI resources not getting assigned.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
