puc.c currently first maps the full spaces from the PCI BAR's and then creates a subregion for each of the com/lpt devices according to the list of known devices in pucdata.c, sometimes more than one per BAR. The pre-autoconf console code creates a bus_space handle (not a subregion of anything) for the console com, which conflicts with puc.c later trying to allocate the larger handle that the console is a subregion (but not a bus_space_subregion) of. Really, puc.c should just be turned on its head, identifying sub-devices first and only then worrying about bus_space mappings, but there's also some device-specific code in there that I can't test, so I was reluctant to do that. -- Soren
