FWIW, I am working on a PXA270 target, and have had to revert this patch
as well.  I hadn't gotten around to tracking down where and why I was
crashing though so hadn't emailed in a bug report yet.  Now seeing as
there's someone else now seeing it too I thought I would chime in with
a "me too".

Rob: CC'd you since you were the author and might have some insight.
Full email in entirety below.
