The title of that bug should be renamed to "Kernel 3.13 still broken on
Radeon HD based desktops and laptops" like Sangeet is suggesting. I used
option "Install new hardware support" on 12.04 LTS and I my system
started rebooting because this step installed kernel 3.13. Important
side-effect was scanning disc drive everytime after reboot (cancelling
didn't help as drive coudn't be mounted).

Similar problem I found during installing fresh 14.04.01 - during
starint X server for isntaller my computer is rebooted.

My system - Motherboard: MSI FM2-A55M-E33 (MS-7721), CPU: AMD A10-5700
APU, GPU: [AMD/ATI] Trinity [Radeon HD 7660D]

Bug is opened 4 months for 14.04 but at least user experience it upfront
but I don't understand why you are introducing this LEVEL of bug in
12.04 LTS if it is already known.

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.
