I am no kernel > expert :( As your driver's callbacks aren't being called, that's probably why this isn't working. Please make sure your pci hotplug driver is working first. Try turning on and off the power to the card slot (in the sysfs directory for the slot) and see if that's working. You also have failed to say exactly what pci hotplug controller you have in your system, what is it? You have to have one, and the driver loaded for it, for any of this to work at all. greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
