Hello,

When I try to disconnect Blue Stereo 200 headset (from mrhandsfree) from 
my PC, if headset was the initiator of the connection, the low level 
(ACL) is not disconnected.
The device is still visible whith "hcitool con".

This happens with BlueZ 4.98 or from git upstream, and kernel 3.4.6.
There is no disconnection problem with kernel 3.2.

I also try to revert change "Bluetooth: Fix RFCOMM session reference 
counting issue" (commit cf33e7 in linux-stable.git) from Octavian 
Purdila in kernel 3.4.6.
With this kernel I do not get disconnection problem.

You can find attached hcidump traces.

Fred
