Subject: Kernel panic on kernel 3.8.x when closing bluetooth dun connection

Hi,

I'm following up with a previous email where I was reporting a
systematic kernel panic when closing a bluetooth DUN connection.

I have made a few more tests:

- Bug happens with all the 3.8.x kernel series, up to the latest 3.8.6
- Bug is not present up to 3.7.x, including the latest 3.7.10
- Bug happens on the DELL E6500 laptop that has a Dell Computer Corp.
Wireless 370 Bluetooth Mini-card
- Bug also happens on a desktop that has a Cambridge Silicon Radio, Ltd
Bluetooth Dongle (HCI mode)

Let me recall that the bug is triggered by connecting to the internet
via a mobile phone, using bluetooth DUN and then disconnecting. Kernel
panics on disconnection (the phone I am using is a Samsung Galaxy S Plus)

- Bug does not happen on the same machines when connecting to the
internet via ppp using a usb-umts dongle

Hope this can helps haunting the regression.

Thanks for the attention,

Sergio
