I am using an Overo Fire CoM with the Palo35 expansion board and the 3.5" LG LCD display.  After turning it on, after about 9 or 10 minutes, the display appears to sleep and there is no way to turn it back on other than to hit the reset button on the expansion board.  From looking at the output from the CoM itself, when this happens, it appears to be executing a function called "panel_suspend".  Has anyone else encountered this problem, and if so how was it fixed?
