请教rehat9启动过程中的疑难问题
借五一假期，我前日更新了我办公室机子的kernel，原来是kernle- 2.4.20，更新后为2.6.10， uname提供的系统信息为：Linux info218 2.6.10 #1 SMP Thu May 5 22:14:28 CST 2005 i686 athlon i386 GNU/Linux
系统更新后曾正常工作了一天，但系统启动时屏幕提示会长时间停留在 “Kernel command line: ro root=/dev/hdb5 elevator=deadline ”，然后直接进入x windows的登录窗口。也就是说，"Initializing CPU#0 ....................."等之后的信息不能显示在屏幕上，我想(应该是init或rc.d等文件出了问题，但我查了一下，没有发现问题所在。 但总之机器是可以正常使用的。
前晚我又试图更新gcc，原来是3.2.2 20030222，我试图更新为4.0版本。我是家里进行远程更新的，在远程发送命令init 6后，过一段时间发现能够重新远程登录，表明系统已经成功重新启动，升级成功，非常高兴。随后便init 0关机。
但第二天我到办公室启动电脑时，发现屏幕长时间停在Kernel command line: ro root=/dev/hdb5 elevator=deadline. 经过硬盘灯在不停闪动，表明系统仍然运作。还可以看到软区和光驱的灯会亮一会儿，经过这一番折腾后，然后就消停了，似乎是正常的系统启动过程。但屏幕仍然停在"Kernel command line: ro root=/dev/hdb5 elevator=deadline". 点击鼠标和敲打键盘无任何反应。
起初我以后系统当了，正准备重新装机。带着侥幸心理从我的本本进行远程登录试试，发现竟然成功了。也就是说，虽然在本地机器上，屏幕上无任何反应，但系统的确启动了。我可以远程登录，安装程序等。 于是我做了一些补救措施，将gcc恢复到3.2.2 20030222，升级XFree86到最新版本，但都无济于是。其中碰到的一个问题是，vim不能启动，说是某些lib文件(*.so.1之类的)找不支，我更新安装了gtk2后解决这个问题。
现在我的机子仍然不能无法从本地进入，启动后屏幕就一直停在"Kernel command line: ro root=/dev/hdb5 elevator=deadline"'上，所以只能远程登录：-)。
希望各位高手不吝赐教，一是让屏幕显示“ Kernel command line: ro root=/dev/hdb5 elevator=deadline”之后的启动过程，就是显示"Initializing CPU#0 ....................."；二是让本地机能够起到x windows，正常使用（我不能够总是远程登录呀！）。
非常感谢！！
下面是我的dmesg信息，供高手参考：
