you can keep every Bluetooth daemon running even if no device is
attached. They will re-init themself if you power-up your internal
Bluetooth device. What I think that happens is that the stopping with
spicctrl is the same as a physical unplug and this causes a kernel oops.
Check if you have CONFIG_BT_HCIUSB_SCO enabled, if yes, disable for now
or apply the attached patch.
