编译内核2.4后死活无法启动，大虾们帮帮小妹吧，花了3天时间啦

pandawlm

小妹使用RedHat9.0，kernel2.4.20-8，想升级为2.4.30，步骤如下：

#cp linux-2.4.30.tar.bz2 /usr/src/
#tar xjf linux-2.4.30.tar.bz2
#ln -s linux-2.4.30 linux-2.4
#cd linux-2.4/
#make mrproper
#make menuconfig

配置的时候在默认的情况下选了以下选项：
1. SCSI device support  --->SCSI low-level drivers  ---> <M> BusLogic SCSI support
2. Fusion MPT device support  ---><M> Fusion MPT (base + ScsiHost) drivers和<M>   Fusion MPT misc device (ioctl) driver
3. Networking support  --->Ethernet (10 or 100Mbit)  ---> <M>   AMD PCnet32 PCI support
4. File System ---><M>Ext3,找不到VFS阿！
#make dep
#make bzImage
#make modules
#make modules_install
#cd /boot/
#cp /usr/src/linux-2.4/arch/i386/boot/bzImage ./vmlinuz-2.4.30
#cp /usr/src/linux-2.4/System.map ./System.map-2.4.30
#rm -r vmlinuz System.map
#ln -s vmlinuz-2.4.30
#ln -s System.map-2.4.30 System.map
#mkinitrd initrd-2.4.30.img 2.4.30
#vi grub/grub.conf

grub.conf内容如下：
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title RedHat Linux 9.0 (2.4.30)
      root (hd0,0)
      kernel /vmlinuz-2.4.30 ro root=/dev/sda2     ----->‘/’在/dev/sda2下
      initrd /initrd-2.4.30.img

#reboot
重启之后出现如下错误：
kmod:failed to exec /sbin/modprobe -s -k block-major-8,errno=2
VFS: Cannot open root device "sda2" or 08:02
Please append a correct "root=" boot option
Kernel panic: VFS : Unable to mount root fs on 08:02

请大虾们救救小妹吧！我快崩溃啦！

try add "alias block-major-8 sd_mod" to /etc/modules.conf and mkinitrd again

SCSI DISK有没有config进kernel？

配置进了内核

如何操作？

Post by daemeon
try add "alias block-major-8 sd_mod" to /etc/modules.conf and mkinitrd again

daemeon

echo "alias block-major-8 sd_mod" >>/etc/modules.conf   #主意是两个'>'
mkinitrd initrd-2.4.30.img 2.4.30

还有，你的grub.conf中kernel,init的路径好象不对吧，

pandawlm

路径不对？都放在了/boot下了呀！

echo "alias block-major-8 sd_mod" >>/etc/modules.conf   #主意是两个'>'
mkinitrd initrd-2.4.30.img 2.4.30

还有，你的grub.conf中kernel,init的路径好象不对吧，

daemeon

JJ，你的grub.conf中，kernel,initrd是在根目录下喔！

pandawlm

是#echo "alias block-major-8 sd_mod" >>/etc/modules.conf   
吗？

mkinitrd initrd-2.4.30.img 2.4.30

#echo "alias block-major-8 sd_mod" >>/etc/modules.conf

还是出现同样的问题。继续求救阿！
