待机状态下CPU占用高

赵家乐

设备环境：（物理机、局域网、0.8.37）

BUG现象：（后台没有负载的状态时，CPU占用较高25%+。因为是笔记本安装风扇会一直全速运行。待机功耗和噪音较大）

出现频率：（必现）

设备信息

cpu信息

进程信息

ssh-top信息

ssh-htop信息

systemd-journal、rsyslogd进程占用CPU较高。看上去都是日志相关的进程。

飞牛技术同学

可以输入journalctl -f 看看会不会大量刷出日志 截图看看具体情况

查看日志。发现快速输出以下日志。提示pcie设备异常。使用笔记本安装的飞牛，只有一个pcie的无线网卡。拔掉再开机，这个问题就消失了。目前CPU占用正常。感谢大佬！！
