Você pode tentar parar e desativar o serviço bluetooth:
sudo systemctl stop bluetooth
sudo systemctl disable bluetooth
Quando eu inicializo meu sistema (sistema operacional Debian), e o systemd atinge o alvo Bluetooth, ele leva 1min30s antes de me informar que a dependência falhou para disk_by_device e para swap.
Por favor, como pode desativar o bluetooth definitivamente?
