Pretty sure I did it right. Just rebuilding now once more

Could it also have something to do with having to add device apic in order for
the kernel to compile now ? I didnt have that before.

I am booting the 2nd image I made just now with the above steps and its slow as
well. Will post the verbose dmesg and sysctl output once its fully booted in a
sec
