modprobe

sudo modprobe ath3k - doesn't say anything

para em:

for i in /etc/modprobe.d/*; do echo $i; cat $i | grep ath3k; done
/etc/modprobe.d/ath3k.conf
blacklist ath3k
/etc/modprobe.d/bumblebee.conf

P.S. se ajudar ... notebook - Acer aspire v3-571g

    

Answer 1

Para corrigir isso, você precisa

sudo rm /etc/modprobe.d/ath3k.conf

Você ainda pode ter problemas causados por um problema de temporização com o carregamento do firmware, mas isso deve ser corrigido em um kernel mais novo que 3.19
