Maybe you could post it. It makes sense if you have on-board PCI devices. : If this is a board specific problem - can we at least add a loader : variable to disable routing, so I don't have to patch the source on : every update and can run a standart boot disk again? Did it used to work when we were re-routing all the time? It would be easy to add this as an option, but maybe understanding your setup might help a little to make our routing code a little smarter.
