No module mptscsi found for kernel 2.6.20.14, aborting.

[root@localhost boot]#

解决方法：

[root@localhost boot]#  cat /etc/modprobe.conf

alias eth1 pcnet32

#alias scsi_hostadapter mptbase

#alias scsi_hostadapter1 mptscsi

#alias scsi_hostadapter2 mptfc

#alias scsi_hostadapter3 mptspi

#alias scsi_hostadapter4 mptsas

#alias scsi_hostadapter5 mptscsih

alias eth0 pcnet32

在scsi的相关部分注释掉即可！

kernel /vmlinuz-2.6.11.10 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.9-1.667.img
原因：
    You have given your new kernel the initrd from the old one in grub.conf....
解决方法：
    You will have to make a new initrd for your new kernel, you can't mix up initrd's and kernel images, each initrd consists of modules copied from the kernel that needs them. Use mkinitrd.
   显然/boot/grub/grub.conf中的initrd项不配套，我用了原内核的initrd。各个版本的内核对应自己的initrd，只需要
cd /usr/src/linux*
make install
即可生成配套的initrd、vmlinz、System.map即可！

问题3：

找不到网卡的驱动：
原因：
[root@localhost modules]#cd /lib/modules

[root@localhost modules]# ls

2.6.20.14    2.6.9-42.ELhugemem  kabi-4.0-0

2.6.9-42.EL  2.6.9-42.ELsmp      kabi-4.0-0smp

[root@localhost modules]# mv 2.6.9-42.ELsmp/  2.6.9-42.ELsmpbak

/lib/modules下的驱动加载不了！

只需要将原来的目录名改回来即可！
