In fact, I watched the LED accross the boot, and it lights on when the following is displayed: [ 19.441103] Bluetooth: Core ver 2.15 [ 19.451982] Bluetooth: HCI device and connection manager initialized [ 19.456402] Bluetooth: HCI socket layer initialized [ 19.497216] Bluetooth: Generic Bluetooth USB driver ver 0.5 So I guess thinkpad-acpi correctly tries to keep bluetooth off, but the bluetooth module re-enables it for some reason. This is even before /etc/init.d/bluetooth is run. -- Yves-Alexis
