    Hi Ben,

    what's the point of calling wake_up_locked(&sem->wait) in
    aio_down_wait? We're already in a wakeup path and end up
    calling __wake_up_common recursively.

    I think it may be one of the cause of my kernel hanging at the
    very beginning.

    When I remove this call things go further but at some point a
    semaphore wait queue gets thrashed and __wake_up_common tries to
    call an invalid callback function.

    Any input appreciated.
