I am wondering if for some reason the suspend/resume actually does a HCI Reset without telling us. The name normally only gets reset to BCM20702A when doing a full reset. Another possibility is that we actually forgot to set it in the first place. I am pretty sure I have intensively tested and that should not happen, but you might just found a corner case.
