    Hi !
    In our sample driver ,
    The system gives panic, if I initialise the semaphore to -1
    [sema_init(&sem,-1)] and
    then try to acquire it by calling down() .
    It gives a kernel panic . what could be the reason for this.
    Where exactly is panic() called?

    could not figure out easily from code.
    Thanks
