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.
