Title:
  omapdss DISPC error: GFX_FIFO_UNDERFLOW, disabling GFX

Status in “linux-ti-omap4” package in Ubuntu:
  In Progress

Bug description:
  Platform: Panda board, 8 layers.
Processor: TI OMAP4

Symptom:  The screen will go black randomly - even when there is activity - and doesn't come back.  The following output can be found on the serial console (when enabled) and the log file:

 [  404.169006] omapdss DISPC error: GFX_FIFO_UNDERFLOW, disabling GFX

To recover the screen, change to another console and get back to tty7: CTRL + ALT + F1 followed by CTRL + ALT + F7

This is a known problem that is currently being addressed by TI.
