I ran
dpkg --get-selections | grep linux-image
to find old installations of the kernel images such as: linux-image3.19.0.15-generic the purged them with this command
sudo apt-get purge linux-image-3.19.0-15-generic
I did this for all old linux-images in the list from the dpkg --etc command above
I deleted all but the current and the next most current, there were two linux-image-extra...etc that needed to be purged as well. These were listed with a "deinstall" parameter in the dpkg --etc list. I am not sure why those needed special attention but the rest auto purged the linux-image-extra...etc packages with the single: sudo apt-get purge linux-image-3.19.0-xx-generic command
I then upgraded to 15.10 and I no longer have the "Reached target Shutdown" hang issue...at this time, caveat it hangs for a few seconds but not indefinitely for me.
These are the only images currently installed now:
