The only time I've seen "hang-like" behavior the system actually opened a 
devshell and was awaiting input.   But based on your log, it doesn't look like 
that is the case.

Run bitbake with -DDD option, you will get considerably more debug information 
and it might help point out what it thinks it is doing.
