[Bug 1562269] [NEW] On Ubuntu touch start bluetooth / stop bluetooth hangs

 

Public bug reported:

When trying to start or stop the bluetooth subsystem, the start or stop
command just hangs.

A couple of upgrades back, we already *had* a similar situation, now it
re-appeared.

However, when Control-C'ing the start command, and then trying it again,
it says "start: Job is already running: bluetooth"

Likewise, when Control-C'ing the stop command and then trying it again,
it says:  "stop: Job has already been stopped: bluetooth"


root@alains-pocket-penguin:~# lsb_release -rd
Description:    Ubuntu 15.04
Release:        15.04
root@alains-pocket-penguin:~# apt-cache policy bluez
bluez:
  Installed: 5.37-0ubuntu5~overlay1
  Candidate: 5.37-0ubuntu5~overlay1
  Version table:

     4.101-0ubuntu25 0
        500 http://ports.ubuntu.com/ubuntu-ports/ vivid/main armhf Packages

What I expected to happen
 start bluetooth should start the bluetooth subsystem, and then return as quickly as possible
 stop bluetooth should stop the bluetooth subsystem, and then return as quickly as possible

What happened instead
  start bluetooth hangs... and after control-C'ing it, status bluetooth is "bluetooth start/starting"
  stop bluetooth hangs... and after control-C'ing it, status bluetooth is "bluetooth stop/starting"
