Hmm, I wonder why you call oldconfig explicitly?
A plain "make -j16" executes "silentoldconfig" if there
is any changes in a Kconfig* file or in .config.
Just double checked and it works as I expected.
So you are asked if there is any new options anyway even
if you skip your "oldconfig" step.
Try this:
git clean -dqfx
make -j16> ../makes
It doesn't work, because "make silentconfig" will say
***
*** You have not yet configured your kernel!
*** (missing kernel config file ".config")
***
*** Please run some configurator (e.g. "make oldconfig" or
*** "make menuconfig" or "make xconfig").

which is why I always run "make oldconfig".
Sure, I could do it only when I need to, but quite frankly, it's much
easier to just always do the thing that works, rather than try
something that doesn't work, do something else, and then re-try the
thing that can fail.

Please read the FAQ at http://www.tux.org/lkml/
the above command does break over here. using the make oldconfig command
seems to be working after I did the make menuconfig.
Now before doing all of this I did make a copy of the entire kernel for
a new system Im building(clfs) so I went into that tree and did a make
oldconfig and(luckily) hit the non responsive oldconfig thing that Linus
had originally posted.
here is a strace of when make oldconfig was not working(with git log at
the top)
http://fpaste.org/317B/
and strace of a git pull today and make oldconfig does not crap out and
starts asking me y/n options:

hope this helps with debugging and such.
