The most likely explanation is that on your system IOMMUv2 is not enabled. That may be a BIOS setting. If your system BIOS setup doesn't allow you to enable the IOMMUv2, then you may be out of luck. I'll attach a patch that adds some extra error messages that should confirm that or point to a different source of the problem.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
