进入Fedora core8一小段时间后键盘鼠标失去响应

coldrainsunc

　　新安装的fedora core 8后还未使用就出现问题，实在郁闷，在此向兄弟们请教：

　　简单介绍一下我的PC：联想的台式机，DELL LCD，键盘是PS/2口的，鼠标为USB口的，以前一直安装有fedora core 5操作系统，未出现任何硬件冲突方面的问题。

　　新安装的fedora core 8，系统启动完毕后进入“首次登录界面”，此时鼠标失去响应（系统加载服务时可以使用），大约两三分钟后键盘也失去响应；重启数次后都是相同的结果。

　　在启动前更启动参数，使用运行级3启动，结果也相似，即开始时键盘可用，约两分钟后失去响应，但系统好象并没有死，因为进入level 3后运行top，程序一直有输出。

　　单用户进入，去“首次登录(firstboot)”，无效果；

　　单用户进入，查看系统日志：

望各位多多指教，兄弟在此谢过^_^

唉，对这种莫名的故障很是头疼！
