每次一启动系统到这里就要卡几分钟，请问高手什么原因？

[hcym]

fstab里面

我是连 / 都设置为0



哪么多码等待高手看看

[sfbi]

有点像一个bug，之前在哪个地方看过类似的问题。

[tivooooli]

好像不是fstab里设置的问题。
从启动上看，就是在loading hardware drivers那里开始，大概要停四个30秒那么长时间
只是显示：
[ 105.002722] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

[ 105.002737] ata3.00: status: { DRDY }
之类的信息。
这次安装用的是ubuntu.cn99.com的源网络安装，会不会是源有问题？（应该可以排除硬件损坏，因为进入系统后是好的，windows启动也很顺畅）

磁盘出错, 是不是物理损坏了

[tivooooli]

问题已经解决，但原因还是不太清楚。
我只是把光驱卸了下来，重装了一下UBUNTU，一切OK。
可能是IDE的光驱和SATA硬盘在一起的问题吧，网上有人这么说。但DEBIAN安装没有任何问题，看来UBUNTU的驱动还是有缺陷。OVER
