Hints are not useful for a card like the 3c509 which supports a mechanism to enumerate cards and determine their configuration. Note that this recent problem didn't result in the card being unusable; it just confused the driver when the detected card was configured out from under it by the PnP system. Clearly there is some failing of ep_isa_identify() to correctly note that a particular card is in PnP mode. Fussing about the PnP system in general is silly when we're talking about the 3c509; if you want to hardcode the card and lock down the resources, take it out of PnP mode already. </rant> -- | Matthew N.
