This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment "phone";
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another program will cause the crash easily.
