You may not use the ibm_acpi driver at the same time as the acpiphp driver for docking. This is because the ibm_acpi driver also tries to handle the dock event notification, and doesn't actually do any hotplugging of the devices. So, you want to set that config option to N. What you are doing above is actually writing to the ibm_acpi driver. I didn't provide a way to do undocking via software. I just use the button on the dock station. You should however, see something in /sys/bus/pci/slots - can you scan your dmesg to make sure that the acpiphp driver is running? You might run it as a module and enable debugging: modprobe acpiphp debug=1 This way we can see if it finds your dock slot and registers the notify handler. Thanks for testing!
