The kernel from your link does not bring up the display. The last
message I think I saw was :

Title:
  Trusty linux kernel 3.12.0-2 doesn't boot on Macbook Pro 8,2

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After upgrading from Saucy to Trusty, the 3.12.0-2 kernel doesn't
  fully boot on my machine. I have to use the older 3.11 kernel to boot.

  The 3.12.0 kernel tries to boot but then seems to fail at some stage.
