yeah I see what your hitting, just experienced what you posted

	make oldconfig
   scripts/kconfig/conf -o arch/x86/Kconfig
   #
   # configuration written to .config
   #

(just sits there)

seemed to not want to go away.(doing a make menuconfig got
make oldconfig to wake up of whatever it was in) as for reproducing
(even though already bisected) seems once make oldconfig starts working 
properly, hitting the above doesn't happen as easily.
