 This looks likely to be the culprit -- uhci attach failed, but left it
 in a state not expected by uhci detach.
 
 This message comes from the x86 pci_intx_alloc when pci_intr_map
 fails:
 
     448 	if (pci_intr_map(pa, handle) !=3D 0) {
     449 		aprint_normal("cannot set up pci_intr_handle_t\n");
     450 		error =3D EINVAL;
     451 		goto error;
     452 	}

 Can you share the output of the following commands?
 
 # pcictl pci0 dump -d 26 -f 0
 # pcictl pci0 dump -d 29 -f 0
 
 Perhaps that will provide a clue about what's wrong with the device's
 PCI interrupt mapping.
 
 Is this problem new?  Does it occur with, e.g., the 9.3 image, or 8.2,
 or any other older versions?
