Hello Frank.

I don't know what's wrong, but I'm also interested in this problem.

Maybe we should take a closer look at 
src/common/lib/libc/arch/powerpc/atomic 
or maybe 
/sys/arch/powerpc/powerpc/lock_stubs.S

I already went through these files but don't see anything wrong. But I have a 
feeling that setting FULL might hide some problem present in these files...
