Estou executando um dos novos NUCs da Broadwell em 15.04. O Bluetooth tem sido "bom" nas últimas semanas (não o usei além de testá-lo com um mouse BT). Ontem comecei a ver o spam contínuo explodir no syslog e no dmesg. Até agora, a única solução que eu encontrei é a lista negra btusb em /etc/modules/blacklist.conf e, em seguida, reinicie.
As mensagens começaram quando a máquina estava sem supervisão, e as últimas atualizações para o udev e para o kernel foram dias antes. Eu tentei reinicializações a frio, em seguida, usando kernels mais antigos, desconectando todo o resto USB, ligar / desligar a inicialização segura - nada. A linha hci0 sending initial HCI reset command failed (-19) do kernel parece ser a chave, mas não tenho idéia do significado de -19 ou de onde procurá-lo. Onde posso encontrar mais informações ou estou faltando algo relevante nos logs?

Eu sei que este é um tópico antigo, mas vou ressuscitá-lo para aqueles que compartilham essa frustração, que continua até hoje ...
Veja este tópico no site da Intel: link
Aparentemente, desligar e desconectar o NUC por alguns minutos corrige o problema. (para sempre?) Espero que isso ajude.
