我只是更新了我的Linux的内核：
[root@localhost ~]# cat /etc/redhat-release Scientific Linux release 6.1 (Carbon) [root@localhost ~]# uname -a Linux localhost.localdomain 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]# / var / log / messages中的最后几项：
Oct 1 10:22:10 wcmisdlin02 wall[21689]: wall: user root broadcasted 1 lines (8 chars) Oct 1 10:22:40 wcmisdlin02 NetworkManager[1866]: <info> kernel firmware directory '/lib/firmware' changed Oct 1 10:22:43 wcmisdlin02 yum[21626]: Updated: kernel-firmware-2.6.32-279.9.1.el6.noarch Oct 1 10:22:53 wcmisdlin02 yum[21626]: Installed: kernel-2.6.32-279.9.1.el6.x86_64 Oct 1 10:23:05 wcmisdlin02 yum[21626]: Installed: kernel-devel-2.6.32-279.9.1.el6.x86_64 Oct 1 10:23:07 wcmisdlin02 yum[21626]: Updated: kernel-headers-2.6.32-279.9.1.el6.x86_64
/var/log/yum.log
[root@localhost ~]# tail /var/log/yum.log | grep "^Oct 01" Oct 01 10:22:43 Updated: kernel-firmware-2.6.32-279.9.1.el6.noarch Oct 01 10:22:53 Installed: kernel-2.6.32-279.9.1.el6.x86_64 Oct 01 10:23:05 Installed: kernel-devel-2.6.32-279.9.1.el6.x86_64 Oct 01 10:23:07 Updated: kernel-headers-2.6.32-279.9.1.el6.x86_64 [root@localhost ~]#
现在它不会启动（就在我看到GRUB的地方，我可以select不同版本的内核（我试过新安装的一个和以前的内核），相同的结果：
Kernel panic - not syncing: VFS: Unable to mount root fs on known-block(0,0) Pid: 1, comm: swapper Not tainted 2.6.32-279.1.1.el6.x86_64 #1 Call Trace: [<ffff ....
我也注意到所有“initramfs”文件看起来像已经更新（这可能是为什么我不能启动到旧的内核了）
[root@localhost ~]# ls -al /boot/initramfs-2.6.32-279.* -rw-r--r--. 1 root root 15227261 Oct 1 10:25 /boot/initramfs-2.6.32-279.1.1.el6.x86_64.img -rw-r--r--. 1 root root 15227720 Oct 1 10:25 /boot/initramfs-2.6.32-279.5.1.el6.x86_64.img -rw-r--r--. 1 root root 15227774 Oct 1 10:26 /boot/initramfs-2.6.32-279.9.1.el6.x86_64.img [root@localhost ~]#
有任何想法吗？
