It isn't misbehaving it just isn't available. MWI is rather different to say pci_set_master() in that it makes a lot of sense for many drivers to ask for it but not care about the results. Something like pci_set_master failing is a big problem and has to be handled (although as we often don't use BIOS PCI services we see fake success in some cases). MWI is an "extra cheese" option not a "no pizza" case Alan - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
