ubuntu16.04系统日志暴增是什么原因？

Question

安装了tensorflow，也有可能是安装了cuda8.0之后，系统日志就开始疯长，kern.log跟syslog两个文件以每秒30M的速度变大，里边大概都是这些内容：

请问大概是什么原因引起的？可否设置关闭类似这样的log的输出？

Answer 1

google了一下: https://bugs.launchpad.net/ub...

Answer 2

安装之后是不是内核也跟着升级了？比如到了4.11？我看了一下上游4.11版一直存在这个问题，目前似乎还在讨论中，唯一有参考价值的回复是有个人说自己安装了个Ukuu，然后问题解决了。不知道是否可以解决你的问题：

sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update && sudo apt-get install ukuu

Answer 3

请问你定位到原因没有，我看网上很多case说的都是让关掉aer的报告；我希望了解一些产生这种日志的原因，比如可能是我的主板、显卡等硬件有问题？还是驱动问题，而不是将这个error关闭视而不见。
