Title:
  regression on 4.3.x: i945/Display corruption (before X, X never
  starts))

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This laptop works with 4.2.0-19 and fails with 4.3.0-2.

  At boot (before X) the display is corrupt - with the entire screen
  shifted halfway across the screen with the kernel boot text mostly
  readable, just shifted over (and some crud at the top).  X doesn't
  start.  Returning to 4.2.0-19 (as now) and it's fine.

  In the 4.3.0-2 world I see the following warning in the dmesg:
