![系统频繁挂起且响应滞后](https://linux22.com/image/1047007/%E7%B3%BB%E7%BB%9F%E9%A2%91%E7%B9%81%E6%8C%82%E8%B5%B7%E4%B8%94%E5%93%8D%E5%BA%94%E6%BB%9E%E5%90%8E.png)
我使用的是 Ubuntu 14.04。几个月前升级的。我的系统一直运行正常,直到昨天开始出现延迟。系统经常会挂起 30 秒(大约或更长),而且我打字时响应也出现延迟。除此之外,系统运行正常。
我用 Google 搜索了这个问题并找到了以下答案:https://askubuntu.com/a/21643/55026。第三点帮助了我,我收到了这些消息kern.log

我已经在 Google 上搜索了错误信息,他们说这可能是硬盘问题。
更新:复制大型文件(电影等)到系统时系统会挂起。但我过去常常忽略它们。
