And if you run it a second time with:
# fsck.msdos -av /dev/sda1

Please unplug everything from this laptop, except power. You need to get the basic setup working reliably first. No external hard drives. No mouse. Nothing, except power.

Skip creating a replacement journal for now, I'll probably see most of it with the shutdown-log.txt I mention later.

That doesn't seem right at all. Do you have some kind of watchdog like process running that causes a reboot if something fails? That's what this sounds like to me, because i is just a SIGKILL for everything except systemd. So it should not reboot.

Read this under the section "Shutdown Completes Eventually"
http://freedesktop.org/wiki/Software/systemd/Debugging/

Follow the instructions exactly. For this you can directly edit grub.cfg if you want, rather than editing it in grub's edit mode which can't do copy-paste obviously. Create the debug.sh (remember to make it executable or it won't work). Reboot so the boot params take effect, and then do a poweroff. That whole poweroff sequence should record a lot of debug information and write it all out to /shutdown-log.txt which you can then post.

Please disconnect the mouse for this troubleshooting so that we're only dealing with the basic system for now.

Now I'm completely and utterly confused :-)

I put in the debug.sh script in place and edited the grub.cfg to add in the systemd debug lines including the enforcing=0.

I tried the poweroff and it worked.  I rebooted tried it again and it worked.  I rebooted again and tried the

echo 1 >/proc/sys/kernel/sysrq
echo r >/proc/sysrq-trigger
echo i >/proc/sysrq-trigger
echo s >/proc/sysrq-trigger
echo u >/proc/sysrq-trigger
echo b >/proc/sysrq-trigger

Just to see what would happen.

It started to do a SElinux relable and got about 20% before it rebooted.  

Now the reason I'm utterly confused is that it got to graphical mode :-(.

I typed Ctrl-Alt-F3 to get to a virtual console and entered

poweroff

and this time the system did not power off, it reset and now I'm back in rescue mode.  Here's the link to the shutdown-log.txt file for this event.

When I was in the virtual console I ran ifconfig and it did not see any network interfaces, it only showed the loopback interface.
