I have exactly the same problem and displays exactly the
above Debug messages:

1. My Linux Server hosting BlueZ NAP crashes with blank console
and frozen keyboard when a client BlueZ disconnects, reboots,
or becomes out-of-range. This happens for clients with Linux or
with Windows XP Pro. My server config is similar, namely:

a. bridge-router-firewall-bluez.
b. Linux 2.6.8.1-mm4-mh1 or
c. Linux 2.6.8.1-mm4-mh2 or
d. Linux 2.6.8.1-mh1 or
e. Linux 2.6.8.1-mh2 or
f. Linux 2.6.5 combo

Incidentally, this setup works very well other than this
problem. I started running this setup 3 weeks ago with
only this problem. My users can surf the net, use email,
etc, with no other problem.

I tried using a Linux Server with nobridge-router-nofirewall-bluez
and this problem of crashes disappears. But network admin is
a bit more tedious without bridging.
