为什么我用用新编译的2.6.9的内核启动不了？显示kernel panic!

Georock

显示 kkernel panic--not  syncing:no  init found.Try  passing  
  init=option  to kernel .系统就不动了？

grub内容贴上来看看，试着传递init=/sbin/init，把文件系统编进kernel了吗？

Georock

我的grub.conf:

       timeout = 10
splashimage = (hd0,7)/boot/grub/splash.xpm.gz
password = --md5 $1$Qs3WfqJL$r0gt8oRM0XylaQpUsN5S90
default = 0
title Red Flag Linux (2.6.9)
        root (hd0,7)
        password *
        kernel /boot/vmlinuz-2.6.9 ro  root=LABEL=/ 3
        initrd /boot/initrd-2.6.9.img
title Red Flag Desktop (2.4.26-1)
        root (hd0,7)
        password *
        kernel /boot/vmlinuz-2.4.26-1 ro root=LABEL=/ vga=785 splash=silent
        initrd /boot/initrd-2.4.26-1.img
title Red Flag Desktop (Console Mode)
        root (hd0,7)
        password*
        kernel /boot/vmlinuz-2.4.26-1 ro root=LABEL=/ 3
        initrd /boot/initrd-2.4.26-1.img
title microsoft
        rootnoverify (hd0,0)
        chainloader +1





把kernel /boot/vmlinuz-2.6.9 ro  root=LABEL=/ 3 改为
  kernel /boot/vmlinuz-2.6.9 ro   也不行.

启动信息：
  Ramdisk:compressed  image found  at  block  0
  VFS:mounted root(ext 2  filesystem)
  Red  hat  nash  version  3.5.7 starting
  mount   /proc  filesystem
  creating  block   devices
  creating  root     devices
  Mounting  root  filesystem
mount:error 19  mounting  ext3
pivotroot:pivot_root(/sysroot,/sysroot/initrd)failed:2
unount  /initrd/proc     failed:2
Freeing  unused  kernel  memory:236 k  freed.
接着就是kernel panic的信息了。

我的分区是ext3格式，记得编译时没怎么动文件系统的选项。

”试着传递init=/sbin/init“
怎么传递呢？

好象是文件系统的问题，使用旧内核，进入系统，然后cha看/usr/src/linux/.config找到关于File System部分的
贴上来看看。
kernel /boot/vmlinuz-2.6.9 ro root=LABEL=/ 3 init=/sbin/init

darkstar_w

root=LABEL=/ 3改成你的根目录所在分区看看如root=/dev/hdax

也许你不应该把ext3编译成模块
因为你的分区是ext3的
在mount它的时候ext3模块还没有加载

have a try

good luck

是阿，将ext3编译到核心。

跟我的问题一样啊~~!
