revision 341006 quite unusable

So I did a checkout of revision 341006 and without any changes to 
make.conf and a trivial "make buildkernel" followed by the requisite
"make installkernel" I get a machine with a black screen and entirely
quite a warm brick. Loud fans.  That is all.  Pretty sure I missed a
big step such as "make buildworld".  May as well forget the idea of
a make -jX foo with any value X other than 1.

I did the exact same process with the sources as provided in RC2 and the 
machine would boot and run fine with kern.smp.disabled=1 otherwise a
warm brick with fans roaring and at least there was something on the 
console.

I did try to load /usr/lib/debug/boot/kernel.old/kernel.debug and seemed 
to get me nowhere. I don't see any docs anywhere on how to load the last
working kernel from forth so I booted the RC2 DVD ( without the dreaded
kern.smp.disabled ) and was then able to mount /dev/ada0s3 on /mnt and
move the old kernel back into place. Bearing in mind that it was built
from the RC2 sources.  Anyways here is output from dmesg from the RC2 DVD :

Note that all four processor cores are available when I boot the DVD but
there seems to be no way to get the same result when I boot from the
installed image.  That baffles me.

What is the diff?

Well here is the diff :

Really a mystery here.
