I have reproduced this error and dumped 6 images of flash
and eeprom at the different stages:

http://saper.info/hg/forth/2010-sep-marker-problem/

You can fetch all the files using Mercurial (http://mercurial.seleni.com) with:

hg clone http://saper.info/hg/forth/2010-sep-marker-problem/

There is something strange when portion of flash memory gets erased for
