I re-ran the test using btrfs (not that I would use it in production, but
just as another comparison).  No lockup after over 24 hours either.

So for now I am converting these boxes to ext4.  I should soon have another
test box with 24 disks that I can reformat as XFS, if something changes and
you'd like me to retest it.

I'd still like to use XFS at some point in the future because this is
running gluster on top, and the gluster people recommend XFS and do most of
their testing with it.
