    Oops, I didn't have /dev/hdb4 mounted at the time ("nocheck" was removed
    from the latest kernels and I had to do some fstab tweaking), and now
    when I try to reproduce it with the 4K filesystem mounted, I can't
    reproduce it. Previously, I reproduced it from (accidentally) /dev/hda2
    (2K) copying to /dev/hdc2 (1K). I also can't reproduce it from /dev/hda4
    (another 4K filesystem on the same drive as where I reproduced it before
    on (hda2)). So, maybe there is also a relation to 4K filesystems.

    So, it seems to depend on SMP being true, copying over different IDE
    buses (maybe), and copying from a non-4K EXT2 filesystem (maybe).

    *boggle* :)
