"alloc_contig_range: ... PFNs busy" on aarch64

    Hi,
    Another slight problem I have with aarch64 Fedora 27 on my
      Raspberry Pi 3, is that it spews out console messages of the form
    
      alloc_contig_range: ... PFNs busy
    
    Essentially, it's the same behaviour as what's described in
      https://bugzilla.redhat.com/show_bug.cgi?id=1387793, but I'm
      seeing different address ranges, like [30f00, 31f00), [31000,
      32000) and [31800, 32800). There are some more variants, but this
      morning, they all have one of the 3 starting points indicated
      here.
    Questions:
    
      Has there been any development related to this issue?
      Should I file another Bugzilla report - seeing as the original
        one is closed with INSUFFICIENT_DATA and belongs to a different
        release?
      Is there anything I can do to get around the problem, or at
        least suppress the error messages? (They kind of get in my way
        right now as I'm experimenting with a framebuffer application.)
    
    Thanks,

    
    - Toralf
