our machine do the aging test. it will crash without any kernel log. it is so hard to analyse。
when the machine stop update display, most of time, the supply current is keep 15mA, but it will suddenly change to 40mA, about 1 second ago, the current back to 15mA.
Every time when our device crash, the supply current is 40mA. then the power button doesn't work, the console couldn't input any word. and it will happen when wifi off( if wifi on, it will not crash but power consumption very high).
