I tried with 1 at the buffer_state and I was able to use the PVR the
same way as setting it to 0. Is there any other test that we can do to
check if it actually reverted back to the standard settings?

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.
