I'm not recompile any version from world and kernel lastest from

root_at_valfenda:/usr # uname -a
FreeBSD valfenda 10.0-ALPHA1 FreeBSD 10.0-ALPHA1 #4 r255503: Fri Sep 13
08:18:27 BRT 2013     rizzo_at_valfenda:/usr/obj/usr/src/sys/VALFENDA  amd64
root_at_valfenda:/usr #

now I'm purge the src dir and re checkout all again.   I'll report some news
