我有一个新的工作站,具有不寻常的高负载平均值.机器规格是：
>至强cpu
> 256 GB的RAM
> 4 x 512 GB SSD连接到LSI2108 RAID控制器(在raid 5中)
我从live cd安装了CentOS 6.5 64位,配置了分区(使用LVM),网络,用户/组,并安装了一些软件,如开发工具和MATLAB.
在启动几分钟后,工作站负载平均值的值介于0.5到0.9之间.但它没有做任何事情.
因此我无法理解为什么负载平均值如此之高.
你能帮我诊断一下这个问题吗？
以下是一些信息：

我没有足够的空间来复制/粘贴’ps axf’的输出,但是：
– D状态中没有进程(磁盘休眠 – 不可中断)
– 除了执行监视工具(如top或iotop)之外,所有进程都处于S状态
在此先感谢您的帮助！
这个错误在
https://access.redhat.com/solutions/508303上游记录,到目前为止解决方案确实是禁用acpi_pad驱动程序.
原文链接：https://www.f2er.com/centos/373571.html在我的系统(IBM Flex x240)上,这会在禁用超线程后发生.
