There isn't any reason that the ET should lock up the system when its IO ports are read. The 'ex' driver is about the most non-destructive probe we've got. It no longer uses the ISA compat shims; its a fully newbus'ed driver. I agree that we need some way to enable/disable newbus drivers in the visual userconfig though. This isn't likely to happen until after 4.0. -- | Matthew N.
