Does the docking not generate a bus rescan event on the SATA bus? If it does, it's just a special case of ACPI drive hotplugging. You can't do it reliably from userspace, but I think Kirsten has been looking at doing it properly in the kernel. > Additionally, currently the dock driver automatically executes the _DCK > method when it detects a dock/undock event.

Otherwise, the hardware should be able to deal with it - every ACPI-based dock I've played with has had some indication to inform the user that the device has disconnected. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
