Troobleshoot 16.04莫名其妙的总系统在几个NUC6i5重启后4小时冻结
我们最近在商店中部署了用于POS显示的英特尔NUC6i5设备，并且在几个设备上遇到奇怪的莫名其妙的冻结。
很奇怪的是，所有设备在启动后4小时都会冻结。 日志中没有任何内容。 没有内核恐慌， kern.log或syslog没有任何kern.log 。
系统显示完全冻结（显示播放的video/应用程序的框架）并且完全没有响应。
我们在超过20个设备（超过100个）上有这个完全相同的问题，来自不同批次的部件，并且在启动后4小时完全冻结（但它不可重现，它不会每天冻结）。 有些设备正在播放MPVvideo，而其他设备则运行铬。 它们不间断运行，但每天都在05h05重新启动。
关于要注意什么，我们有点无能为力？ 我们测试了RAM + DISK，一切似乎都没问题。
有没有什么可以解释这种完全冻结？ 为什么在启动后4小时完全相同？ 我们可以启用详细模式吗？
谢谢！
更新2017-02-27：
终于得到了适当的追踪！ 看起来我正在遇到这个问题：

但目前还没有找到潜在解决方案的线索。
