Bluetooth controller not detected after resume from suspend [Qualcomm Atheros AR9285 Malbec Bluetooth Adapter]

[Nikita B]

It's very familiar to Bug #1788807.
I'm on 19.04.

How can I help to solve it?

1) $lsb_release -rd
Description: Ubuntu 19.04
Release: 19.04

2) $ apt-cache policy bluez
bluez:
  Установлен: 5.50-0ubuntu2

        500 http://ru.archive.ubuntu.com/ubuntu disco/main amd64 Packages
        100 /var/lib/dpkg/status

3) Expectations: work as designed - no issues.
4) after resume from suspended state device is no longer available
- if open gnome (UI) bluetooth manager in journal:

Can you do dmesg | tail -30 in terminal after resume from suspend?

[Daniel van Vugt (vanvugt)]

I don't think the log message "tracker-miner-f[1357] ..." is related to Bluetooth.

Can you say what "Bluetooth device" is not detected? Are you talking about a particular Bluetooth peripheral, or is the Bluetooth icon itself missing?

[Jeremy (wa113y3s)]

Daniel, it appears that the bluetooth adapter is not being found after resume. The Currentdmesg.txt showed

[ 4.140510] usb 6-1: New USB device found, idVendor=0cf3, idProduct=311d, bcdDevice= 0.02
[ 4.140515] usb 6-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 4.140519] usb 6-1: Product: Bluetooth USB Host Controller

But the 0cf3:311d device isn't showing in the lsusb results in the description

[Daniel van Vugt (vanvugt)]

Thanks, apparently idProduct=311d means:

  Atheros AR9285 Malbec Bluetooth Adapter

So if it is on the same board as the AR9485, it's at least a different chip.

This change was made by a bot.

[Kai-Heng Feng (kaihengfeng)]

Looks like it's already gone during boot:
[ 6.687752] usb 6-1: USB disconnect, device number 2

q: - Can you do dmesg | tail -30 in terminal after resume from suspend?

2Jeremy (wa113y3s):
a: First of all thank you for your reply! Yes, I will do it immediately as soon as will find the correct way to reproduce it. The thing is that few days ago I turned on the laptop (HP Pavilion g6) and few times made it suspended but backed from work today I found that rfkill list now return this bluetooth adapter.
{code:java}
~$ rfkill list
0: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no
4: hci0: Bluetooth
 Soft blocked: no
 Hard blocked: no
{code}

So, I will try to find the absolutely way to reproduce it. Probably I need to connect it with headset. When I'm trying to connect happens this (via journalctl -f):
{code:java}
Pukhlya kernel: Bluetooth: hci0: command 0x0408 tx timeout
aug 06 20:38:19 Pukhlya bluetoothd[942]: connect error: Connection refused (111)
aug 06 20:38:21 Pukhlya kernel: Bluetooth: hci0: command 0x0408 tx timeout
{code}

q: - Are you talking about a particular Bluetooth peripheral, or is the Bluetooth icon itself missing?

2Daniel van Vugt (vanvugt):
a: - First of all, thank you for your answer too, Daniel! No, it's not about missing icon.
It's more about unstable behavior of bluetooth adapter.

So, I put more details here...
On Dabian 9.7-10 I've got exact the same problem with bluetooth:
Works>Suspended>No device at all.
So, I got very positive experience on another machine (PC) with Ubuntu and I reinstalled the OS to Ubuntu - but things are getting worser - I can connect the headset not every time, just every other.
This is what happens if via gnome UI bluetooth manager turn b_adapter off and on:
{code:java}
Bluetooth: hci0: urb 00000000222cb6a5 failed to resubmit (113)
aug 06 20:53:33 Pukhlya systemd[1]: systemd-rfkill.service: Succeeded.
aug 06 20:53:38 Pukhlya bluetoothd[942]: Failed to set mode: Failed (0x03)
{code}

2Kai-Heng Feng (kaihengfeng):
a: - Thank you for your attention to details.
Yes, looks like.

So, thank you all. But what to do except Jeremy's ask to collect log?

[Kai-Heng Feng (kaihengfeng)]

Seems like nothing wrong from the dmesg?
