Others may disagree, but I am of the opinion that all ide chipset and hard disc related drivers should be compiled directly into the kernel instead of getting loaded as a module. When you load the piix module the kernel is being asked to make some major changes to an IDE subsystem that has already been initialized by the generic PCI IDE driver and is in use. The kernel may balk at that and refuse to touch a busy device. When specific IDE chipset drivers are compiled directly into the kernel those drivers will superceed the generic driver and initialize the ide system properly the first time around. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
