Alpha has issues with hoses. That said, this might break some things. :( If nothing else, it makes it nearly impossible now for people to get the names of hints to override things like PCI routing via tunables correct. I would prefer a structured solution that preserved the status quo on machines w/o multiple domains. Maybe have the unit number be something like domain * X + bus number, where X is some arbitrary constant like 100 or 1000 (those are better for human parsing). -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
