I can't believe it but while waiting at the hospital, I had plenty of time
to do a binary search on CVS to see when the edb7312 broke. Not a
whole lot of thought -- just CPU time and free wireless.

It have it narrowed down to sometime on 6 Nov 2007 beterrn 11:00 and
22:00 according to the CVS times.

EDB7312 STATUS
=========================
rtems-2007-09-01 -runs
rtems-2007-10-01 -runs
rtems-2007-11-01 - runs
rtems-2007-11-04 - runs
rtems-2007-11-06 00:01 - runs
rtems-2007-11-06 11:00 - runs
rtems-2007-11-06 22:00 - FAILS
rtems-2007-11-08 - FAILS
rtems-2007-11-15 - FAILS
rtems-2007-12-01 - FAILS
rtems-2008-01-01 - FAILS

Attached is the diff I have for that timeframe.

I think this diff has your Thumb support changes. I am hoping that
you can see what small bit is wrong.
