Bug Description

=== SRU Justification ===
[Impact]
Bluetooth (Atheros) won't connect after resume.

[Test Case]
Suspend/resume XPS 9360. BT controller is not functional now.
With the fix, user confirms the issue is fixed.

[Regression Potential]
Low. Limited to Atheros BT. No regression report so far since Hans'
patch got merged upstream.

=== Original Bug Report ===

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.

Hi.

This sounds like a problem with your Atheros wireless/bluetooth chips. Other people are discussing the same problem with the Dell XPS 13 9360 here:
 https://www.dell.com/community/General/XPS-13-9360-Bluetooth-stopped-working/m-p/5092216

However a problem that low-level is usually a kernel or firmware problem (if not hardware). Especially if restarting BlueZ (bluetoothd) makes no difference. So I'm reassigning this to the kernel.

If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed-artful'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

I've experienced this issue with bluetooth being unavailable after a suspend for a quite long time (Ubuntu 18.04, 18.10). Sometimes after a resume I think I'm even unable to connect to the wifi.

I have however found a trick that allows me to fix the bluetooth (on my machine) without the need of a reboot.

To get bluetooth (and wifi) working again I do the following steps:

1. Resuspend the machine
2. Disconnect AC charger if connected and reconnect it. (Not necessary if running on battery power)
3. Resume
4. If bluetooth still not available repeat steps 1-3.
