Title:
Dell XPS 13 9360 bluetooth (Atheros) won't connect after resume
Status in linux package in Ubuntu:
Incomplete
Bug description:
Sometimes after sleep/resume bluetooth won't reconnect to any device.
I can see this in dmesg:
[13129.890580] Bluetooth: hci0 command 0x0c1a tx timeout
I tried:
1. sudo hciconfig hci0 reset
Can't init device hci0: Connection timed out (110)
2. tried reloading modules:
sudo rmmod btusb
sudo rmmod btrtl
sudo rmmod hci_uart
sudo rmmod btintel
sudo rmmod btbcm btqca
sudo rmmod rfcomm
sleep 1
sudo modprobe btusb btrtl hci_uart btintel btbcm btqca rfcomm
no luck.
3. restart bluetoothd - no luck
Only reboot helps.
Laptop is: Dell XPS 13 9360.
