Yes, I remember seeing that happen with the downstream code.  I was wondering why that was instead of mapping everything and then following that with PTR_AND_OBJECT for the pointer specifically.  Anyways, maybe we could only mark HAS_DEVICE_ADDR descriptors as AWAYS?  Would that help avoid the problem?
