Subject: tty_register_device NULL pointer dereference in 2.6.31-rc4

Hello Alan and Marcel,

this morning i got a NULL pointer dereference in tty_register_device() that
looked similar to the one, i posted here on 03-jun-2009:

http://marc.info/?l=linux-bluetooth&m=124404919324542&w=2

As the boot sequence stopped after this point, i was only able to take a
picture of it - see attached jpg.

I was able to shut down the system gracefully by pressing the power button.

The problem emerges really seldom.

Any idea?

Regards,
Oliver
