[AMD]' device =3D 'Starship/Matisse PCIe Dummy Function' class =3D non-essential instrumentation Since these devices serve no purpose (no driver attaches) I have enabled the reporting of suich devices only for verbose boots (a diversion from the patch provided in the PR). A verbose boot will now display such devices as: pci4: at device 0.0 (no driver attach= ed) PR: 263469 Reported by: jfc@mit.edu (John F.
