Comment # 6 on bug 904769 from Stefan Seyfried

bluetoothd gets started through dbus activation, maybe it did not get removed
correctly?

please provide the output of

systemctl status bluetooth.service
ls -l /etc/systemd/system/dbus-org.bluez.service
ls -l /etc/systemd/system/bluetooth.target.wants/bluetooth.service

Basically both files should *not* be present.

Then, please do (as root):

systemctl enable blueotooth.service
systemctl disable bluetooth.service

and paste the complete output of these two commands.
