Important!!!

The Acer E5-551G-T7GR in not the same Device like a E5-551G-T79U!!!! Reinier wrote: "...a new Acer A10 - E5-551G-T79U and..."
ON my Acer E5-...-T7GR you have two Modes to Install a Operating System: BIOS (Best way for Linux only Systems) or UEFI (for Windows 8.x required -Dual Boot Systems). I have only testet The BIOS Mode- i do 'nt need Windows... In the Internet i have seen that The "Firmware Bug" is a Powermanagement Problem and will not crash the OS. (I forgot the URL...) 
I hope it is helpfull for You.

Title:
  I have the same issue (Firmware bug cpu 0 invalid threshold interrupt
  offset) in 14.10

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  On my new Acer E5-551G-T7GR is the installer crashing. The Device have
  a AMD A10-7300 Quadcore CPU and a Radeon R7 M265 Graphics Card with
  2Gb dedicated VRAM. Installed RAM is (factory default) 8GB.

  Tested with x86 and 64bit (AMD) Image.  Ubuntu 14.04 (x86) is
  succesfull running on the Device, without the new Synaptics Clickpad.
  On 14.10 alpha the Clickpad is running....

  Installation: from a USB Stick, to prepare the installation, i am
  using UNETBOOTIN. The Same Stick i have used for a another computer to
  install. The Os for Unetbootin is Ubuntu 14.04 on a Aspire 1535.

  If i am booting the new Acer, the Unetbootin screen comes - if iam
  using default or a another point- the same- after two screens of
  messages- a crash. I have a photo from the last crashsreen with
  "cryptic" messages.

  You need more or another information, please contact me, the Acer
  Laptop is unused and we can do experiments with him...

  Thank You 
  David
