The problem is back. This time I let the restart process wait for
several minutes. See this output.
peddecke@omer:~$ sudo service bluetooth restart
Job for bluetooth.service failed because the control process exited with error
code.
See "systemctl status bluetooth.service" and "journalctl -xe" for details.
peddecke@omer:~$ systemctl status bluetooth.service

Seems the same problem where killing doesn't work.

Title:
bluetoothd hangs and cannot be killed
Status in bluez package in Ubuntu:
Incomplete
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
When having a bluetooth headphone (JBL Live) connected using the A2DP
pulseaudio sink, the output sound suddenly stops during a music
streaming of videocall session. Sometimes just disconnecting and
reconnecting the headphone works, but some times reconnection is not
possible anymore due to the hanging of bluetoothd. Bluetoothd still
appears in the processes list, but cannot be killed, neither with
"sudo service bluetooth stop" or "kill -9":
$ ps afx | grep blue
9597 tty2 Sl+ 0:01 | \_ gnome-control-center bluetooth
5405 ? Ss 0:00 \_ /usr/lib/bluetooth/obexd
10694 pts/0 S+ 0:00 \_ grep blue
20548 ? Ds 0:03 /usr/lib/bluetooth/bluetoothd
All programs keep working normally, only bluetooth is affected as well
as the bluetooth settings page.
The only solution is a hard reboot. A soft reboot doesn't even work:
the systems keeps trying to end the bluetoothd process so one needs to
press the power button for a few seconds to terminate the process.
$ bluetoothd --version
5.48

nice for over one year now just like previous versions.
