I upgraded to LE 12 yesterday.
Before that I had sudden reboots maybe once or twice a week but after the upgrade it's every 8-10 minutes. It doesn't matter if I am doing nothing, watching something from my NAS or stream something. It just reboots. Even if I do nothing after the reboot it happens again after around 8-10 minutes.
The crash log is Chinese to me and it is sooo long

Maybe someone knows what to look for
