Title:
  [regression] No DVI output on the PandaBoard with kernel 3.1.0-1402
  -linaro-lt-omap

Status in Linaro Texas Instruments Landing Team:
  New
Status in Linaro Ubuntu Evaluation Builds:
  Confirmed

Bug description:
  Just upgraded my packages, this pulled in linux-image-3.1.0-1402
  -linaro-lt-omap. After a reboot, there is no output on the DVI
  monitor. After restoring the boot partition from yesterday's backup
  (switching back to 3.1.0-1401-linaro-lt-omap), the DVI output works
  again.
