    Hello ,

    Yes. That I was trying to say.
    For example, the Windows does not show the blue screen in such
    situations. In my practice I saw many times the situation of panic()
    when file system was not fsck'd.
    Actually it may even lead to security holes. E.g. a user may change an
    fs somehow to make it loop in panic forever...
