  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]
