Sporadic iMX6DL Thermal shutdown

I have a custom board with iMX6DL and Linux 3.14.28.


The board was idle (only serial console working) -- and suddenly I received a thermal warning..


Touching the iMX6DL -- it was running very cold (no way it was 175 degrees!)


Any idea why this would happen?







Dump on the console:


System is too hot. GPU3D will work at 1/64 clock.
