Because there is so many drivers, maybe you could prepare some regression tests designed to check changed things. This will allow people to test your changes - it is not very easy now if we don't know what we're looking for exactly PLUS those drivers aren't marked MPSAFE by default. -- Pawel Jakub Dawidek pawel_at_dawidek.net UNIX Systems Programmer/Administrator http://garage.freebsd.pl Am I Evil?
