昨天安装了Fedora 12 64位，安装时启动内核时显示下面的信息，我当时没管，现在每次开机都会有这样人信息，然后过几分钟才能进系统，在网上找了半天，BIOS刷了，内核也升级到最新2.6.32.11-99.fc12.x86_64了，还是老样，是怎么会事阿？有哪位兄弟帮忙解决下？不会是硬盘坏了？以前装F10什么的都好好的阿！！

输入：dmesg |grep ata1.01
显示如下结果：

这表示ata1.01对应的是我的DVD光驱，是Phlips的，这个意思是我光驱有什么问题？可是我以前一直好好的呀，是不是内核不支持或不兼容的原因，请这里的朋友帮忙分析下，谢谢！

唉，估计这个问题是内核和硬件不怎么兼容的原因，看以后新的内核能不能兼容了
以前装32位Fedora 12一点问题都没有的
