Same problem!  Here’s the workaround I found.  Hopefully my efforts will
assist someone else, and point to a permanent fix.

Hardware:
Mobo:	MSI A78-E35
BIOS:	E77221AMS V30.2
Build Date:	02/21/2014
CPU:	AMD A8-5600K APU with Radeon HD Graphics
Mem:	ADATA XPG V1.0 DDR3 1600, 8GB
PS:	680W

(Installing Ubuntu 14.04 server from CD but assume the results would be
the same via USB load)

After reading a post somewhere where the writer thought that the issue
might be related to an “inactivity” timer and said he had some level of
success with continuously moving his mouse during boot, I tried some
combinations of this and have been able to boot and make a stable
environment to work in.  Being a complete Noob to all of this, I am not
sure exactly why this works, but it is repeatable and might help lead to
something that would help sort this out.

I was able to run through the entire server load process by continuously
moving my mouse during the entire process.  Yes you need to type and
make selections to configure your server while constantly moving the
mouse, and no I didn’t try stopping because I wanted to get it loaded.
It went flawlessly!  A real PITA, but it worked.

Next I found that I was able to boot by holding one of the <SHIFT> keys
the entire time the system is booting, but I get varying results.  Seems
like about 4 out of 5 times through the boot process, I am presented
with a small font login prompt to my server.  As soon as I release the
<SHIFT> key the system reloads and it’s time to hold the shift key
again.

About the 5th time through, I get a text menu that looks like this:
*Ubuntu
 Advanced options for Ubuntu
 Memory test (memtest86+)
 Memory test (memtest86+, serial console 115200)

When this text menu appears, you can release the shift key and work
without holding it throughout the rest of the process.  Now, if I just
select Ubuntu, I go back into the boot loop.  Hold the shift again!

In the Advanced Options menu, I get two options;
*Ubuntu with Linux 3.13.0-24-generic
 Ubuntu with Linux 3.13.0-24-generic (recovery mode)

Selecting the Non-Recovery option takes me back to the boot loop, but
selecting the Recovery Mode option gives me a colored text Recovery menu
with eight options, all of which seem work with no problem.  At this
point I select the first option, <resume>, and <ok> on the following
screen that warns that “graphic drivers require a full graphical boot
and so will fail when resuming from recovery”.

Now my server (RIX-ubuntu1) boots to a large font prompt:
Ubuntu 14.04 LTS RIX-ubuntu1 tty1
RIX-ubuntu1 login:

At this point I am able to login normally and the server will run
without issue until it loses power, needs to be reloaded for
maintenance, or any other reason you might have.  This looks like a
work–around, not a fix but it has allowed me to work in 14.04 without
any other issues.

I would love to know if this is repeatable for anyone else, and if some
of you smarter more experienced users can use this to further refine the
quest for a fix.  Enjoy!

Title:
  Ubuntu 14.04 suddenly reboots when booting from Live USB AMD A8 6600k

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a custom built AMD System with the following hardware currently
  running on Linux Mint 16 :

  AMD A8 6600k with Integrated graphics | MSI-FM2-A55M-E33 Motherboard |
  Kingston Hyperx Blu 4GB RAM | Corsair VS450 PSU

  Today when I tried to install 14.04 amd64 iso using a bootable USB,
  then the system rebooted. Any further attempts in installing it
  resulted in the same bug. As soon as I open the "Ubuntu installer"
  application and click "Continue" button then the system restarts after
  2-3 seconds.

  I asked the same on AskUbuntu and some more guys reported the same
  problem with AMD APU, so I believe it to be a genuine bug and not just
  with me.

  The BIOS version is the latest one downloaded from MSI official
  website which is version 11.5.

  Also an Interesting thing is that this bug is common with the latest
  iso of Arch Linux too, but when booting older distros like Linux Mint
  16 from USB, then everything works like it should, so it might have
  something to do with the newer 3.13 Kernel version.

  I am not an expert, but I can surely tell that only the newer distros
  are affected by this bug as reported by some other guys at AskUbuntu
  and the fact that Arch which is running the newer Kernel is having the
  same bug, so it probably has something to do with the newer Kernel,
  but I could be wrong.

  This bug is not letting me install Ubuntu 14.04 on my hardware and it
  is affecting a few more users too. Here is the AskUbuntu thread :
  http://askubuntu.com/questions/449391/unable-to-install-ubuntu-14-04
  -pc-restarts-after-i-click-continue-button-in

  I hope this gets fixed soon or with the 14.04.1 upcoming July release.
