    We found this bug actually through a code review by random. Since
    (un)fortunately the queue pages were layouted in order, we've not
    seen it earlier. It's certainly a bug and can cause kernel panic
    if above observation is not met, probably in stress situation
    of system. That means the "former" code accesses next page that
    it has not allocated.
