There may still be an underline bug, but the "bootz ${loadaddr}" issue i showed in that post was fixed very late in the v2013.07, i forget the commit, it may have been a day or two right before. So looking at your pastebin.com log: "U-Boot 2013.07-rc2-00044-g1d28a6a" it might be worthwhile to re-test with v2013.07 final, specially since your using bootz... (I've already been shipping a bootz enabled u-boot v2013.07 for the beagle-xm to end users)..
