I don't think that's right either... register 6B is an IDE interrupt routing register, not the interrupt itself. If the iosapic system is supposed to remap the register, I don't think it is and I don't know where this is supposed to happen. I hope we can do all of this using just a PCI quirk. > i'd like to see this code too. why not commit it to the tree? it's not > like it works at the moment and things would get broken. I've committed it, and it definitely does not work, but I don't think it'll break anything either. This is mostly mkp's code. - Alex -- Alex deVries, Principal Solutions Architect, The Puffins at Linuxcare 613.562.2759 tel alex@linuxcare.com, http://www.linuxcare.com/ Linuxcare, Support for the revolution.
