引导错误消息

Question

在系统启动时，我将收到以下错误消息。这个系统需要很长时间才能启动，我不明白它在说什么和为什么。操作系统最近已经安装(3周前)。下面是/var/log/dmesg文件的最后几行。请让我知道是否可以解决这个问题。谢谢!

Answer 1

这看起来是一个硬盘错误(因为ATA错误)。当我遇到这样的错误时，对我起作用的是加载到可引导的cd并运行。

fsck /dev/sda1

这修复了阻止我的朋友系统启动的文件系统问题。

我也会在驱动器上进行智能测试，看看是否需要更换。

Answer 2

我只能猜测这个问题与硬件有关，因为日志显示了与磁盘联系的非常多的终端错误。检查计算机的内部连接。

如果不是那样的话，那么您就有严重的问题需要报告为bug(但是首先检查电缆)。对于这样的问题没有真正的答案，就好像它是一个bug，它只是需要有人来修复。详见此处：
