    Subject[PATCH] spinlock not locked when unlocking in atm_dev_register
    Date
    If you compile the kernel with SMP and spinlock debugging, BUG() will be 
    called when registering your atm driver, since the "atm_dev_lock" spinlock is
    not locked when unlocking it.

    kernel 2.4.18

    Regards,
    Frode
