Title:
  Ubuntu server 14.04 can't boot up  after  UEFI installation on
  Avoton-B0

Status in intel:

  Fix Committed

Bug description:
  Label: edv01  （Edisonville）
  BIOS: EDVLCRB1.86B.0033.R00.1311200915
  Processor: Avoton B0
  Kernel version: 3.13.0-23-generic  （Ubuntu14.04 Server Daily）

  Details:
    Ubuntu server 14.04 can't boot up after UEFI installation, the screen is freeze, but system can response to "Ctrl + Alt + F(1-7)". 

  the Graphic ID:
  01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] [1002:68f9]

  the root cause is:
  After UEFI installation, Ubuntu server 14.04 doesn't contain Radeon firmware in /lib/firmware defaultly which is necessary to initialize Radeon graphic card.
  If I copy Radeon firmware manually, this system can boot successfully.
