Public bug reported:

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 at ubuntu-laptop:/home/ubuntu# lsb_release -rd
    Description:    Ubuntu lucid (development branch)
    Release:        10.04
And the bluez version is 4.60-0ubuntu5.
