Kown issues.  XFS uses slab pages (as you noticed below), networking
code doesn't like that.  DRBD has been tripping the same issue.  We need
to come up with a consensus about what type of pages can be used in
block I/O requests.  The drbd folks promised to get this discussed on
lkml but I haven't seen a discussion yet - so let's do it now.
