Всё работало нормально и вдруг, ВНЕЗАПНО, начались проблемы. Загружаешь машину - работает нормально - постоит некоторое время без активности - проблемы. Подключаю уши.
Вот журнал при попытке включить bt через blueman-applet (версия 2.0.5)

Пробовать рестартовать bt службы и вообще килять руками все bt процессы в системе (искал по имени с паттерном blue). Ничего не помогает. Ребутаешь машину - работает. Куда копать?
