Comment(by pgf):

 {{{
 <pgf> cjb: more thoughts: http://www.mail-archive.com/linux-
 kernel at vger.kernel.org/msg243183.html
 <pgf> so len is saying that it should be cache consistent.  but recall
 that mitch is already
 suspicious of cache coherency on this processor, it could well be a
 problem area.
 <cjb> k.  tell the bug rather than me.  :)
