This is the place that I have been bitten. In 5.x (I don't know
about 4.x off the top of my head) you have to type "shutdown -r
now" and NOT "shutdown now" The later keeps using your old
kernel which is what you are trying not to do. It was an new
system in a huge mess so I just reinstalled instead of trying to
fix the problems.
