Hello, first of all, I'm using a kernel with bluetooth-next.git because my device ids where missing in the driver and the patch hasn't made it upstream yet. Hardware: Acer Aspire E1-572-54204G50Mnkk Bluetooth/Wifi combo: Atheros QCA9565/AR9565/QCWB335 ath9k/ath3k I did 20 reboots but bluetooth worked only 7 times of it. When its not working dmesg shows "Bluetooth: Loading patch file failed". Full dmesg: http://paste.ubuntu.com/6685680/ Yours sincerly Joshua
