What output will be produced by the following command (should be invoked
from your kernel compile directory, /sys/amd64/compile/<KERNELNAME> if
you compile manually or /usr/obj/usr/src/sys/<KERNELNAME> for 'make
kernel' builds; looks like you <KERNELNAME> is NAWAK):

And what is inside the file 'machine/specialreg.h' when you're sitting
in the same directory?

I'd expect that 'make clean && make kernel' invoked from /usr/src
should fix your problems, but may be it is not the case, so information
requested above will be helpful.
