System Specs:

ASUS Sabertooth 990FX (with the latest BIOS)
AMD FX-8120
AMD Radeon HD 7950
240GB Seagate SSD (20GiB / partition)
2TB WD HDD (/home)

I have installed Ubuntu 14.04 three times and each met the same fate.
The first time you boot into the system after installing it, it works fine (maybe). However, after you reboot the system it will fail on such a grand catastrophic scale that you can't even boot into recovery mode since that will begin spamming error messages quickly as well.

It does not output anything to logs during these errors so the only
thing you have to go by are screenshots of the errors. In general the
errors are all indicating issues with systemd-udevd.

I also had similar problems in Ubuntu 13.10 (I'm not sure if that still
applies but I will soon find out), plus some extra problems. Ubuntu
13.10 fails at installing grub and the grub-efi-amd64 and outputs tons
of errors regarding efibootmgr.

It isn't related to the kernel since Ubuntu 13.04 with kernel 3.12 works
perfectly. It also doesn't seem to be related to firmware since I use
linux-firmware-1.117 on Ubuntu 13.04 as well. It may be a bug related to
efibootmgr and systemd.

** Affects: efibootmgr (Ubuntu)
     Importance: Undecided
         Status: Confirmed

** Affects: linux-firmware (Ubuntu)
     Importance: High
         Status: Confirmed
