    As said I've tried 2.6.0-test9 [UP, SMP] preemp and SMP non preempt, all with
    the same behaviour, that means immediate machine freeze whenever the usb
    bluetooth dongle is removed from USB port.
    I've also got crashes whenever I've turned off the machine, with bluetooth and
    hci_usb modules loaded.
    I've wrote down the message (by hand, so errors are possible) , hoping that
    this can help. If it's possible to get the full message, please let me know,
    a part of it has scrolled out of the screen (i can use a serial port
    terminal, if needed).

    here is the trace:

    Hope this help,
