Bluetooth blues - need advice

[castalla]

I'm going nuts with a bluetooth problem. To keep it short:

1. Bluetooth installed + bluez-utils

2. BT speaker paired and working .... UNTIL

3. Speaker switched off, AND

4. Maybe 10-20 secs. the Pi locks up, loses connection to network.

5. Only solution is to reboot.

I had assumed that the system would accept the bt signal loss - obviously not.
Does anyone know a fx for this? Otherwise, I can't see bt audio being of any use on the pi.

here's the last few moments of dmesg before the crash - can't see anything of any use. though.

Am i missing some config option somewhere in the bluetooth files?

Help gratefully accepted.

For what it's worth - I've stoped the disconnecting by adding this to the audio.conf file:

Enable=Source,Sink,Headset,Gateway,Control,Socket,Media

I need to investigate this further!
