Bluetooth не включит на Lenovo G510 с Ubuntu 14.04 LTS

Это работало только вчера, и теперь я вижу greyed значок на панели и включении, Bluetooth ничего не делает. Я проверил rfkill и это не заблокировано.

dmesg | grep Blue производит это:

hciconfig hci0 up просто испытывает таймаут.

Какие-либо идеи?
