Thanks for the confirmation. The voltage regulator supplying the CPU (reg_dcdc2) has a 25 mV step size, so you could see if a smaller change to the OPP is enough to make the board stable. I assume you are powering the board with a reasonably stable power supply? In that case, it would be good to apply your change upstream, in case any other Cubieboard 2 users are experiencing crashes. If you want to submit a patch, I would suggest overriding the OPP table in the board-specific DTS. See here[1] for an example of a board that does this.
