so the trouble is that the DLCI 0 will never gets closed and so the
L2CAP PSM 3 will never be close and so on the ACL link can't be closed.
Right now I am not sure what device is buggy here. The BlueZ or your
phone. Please install a 2.6.8-rc2 vanilla kernel and try again and I
need a binary dump of the full communication from your phone to BlueZ.
Do this with "hcidump -w <file>" as root.

Regards

Marcel
