Bluetooth can't be turned off correctly

[Chao Deng]

Binary package hint: bluez

I meet a problem that I can't turn off Bluetooth correctly on ARM platform with Ubuntu Lucid.

If the bluetooth device is under "UP RUNNING PSCAN ISCAN" mode, I have to run "hciconfig hci0 down" twice to turn off it. Following is the state information:

[/LOG]
At first time, it changes the mode from visible to invisible. Then at second time, it goes to off mode. It's not reasonable. I have try it on Ubuntu Karmic, it works normarlly. (From "UP RUNNING PSCAN ISCAN" to "DOWN" mode directly with command "hciconfig hci0 down")

The release of Ubuntu that I use is Ubuntu Lucid.
    root@ubuntu-laptop:/home/ubuntu# lsb_release -rd
    Description: Ubuntu lucid (development branch)
    Release: 10.04
And the bluez version is 4.60-0ubuntu5.

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
