The e1000/em driver was recently modified (heavily).  I saw the large
number of commits come across in a csup a few weeks ago, and there's
even more coming across in recent days (~38 hours ago):

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/e1000/

This is the 2nd problem report to come in about the recent e1000/em
changes.  Because of this, I've avoided building kernel on all of my
systems, and would recommend others avoid doing the same until these
problems can get worked out.

Jack, can you shed some light on what's going on here?
