Alphas intialize IO ranges on chips that aren't configured on PCI-PCI bridges and FreeBSD doesn't check the path. Therefor a driver may access io addresses that aren't configured, or configured differently enough to trap. The whole story with FreeBSD PCI code and bridges on alpha systems is very unsatifiying. The main point is to get our PCI layer to do a path check and refused unavailable ranges, the other point is to get more drivers compatible with memory ranges. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
