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.

This is a known issue.
It comes when the screen resolution is set too high for the system.
Mine does it all the time (6 layers).
Speak to Rob Clark for more information.
