[Nexus 7 General] helloworld1:
I did a factory reset of the device, connect to wiki didn't set up google account, no extra apps installed. Upgraded to 4.1.1.

Every minutes or two, the device will reset itself and sometime it will get stuck at X. Press power button for 10 seconds and it will reset. However it just keeps resetting, I can't stop that.

I enabled the usb debugging and do a adb logcat and get the follow message before it reset:
