LFS6.4无法启动。sata硬盘

启动错误如图所示。我装在sda3上面。
我怀疑是不是我的sda3以前是reiserfs，后来格式化成ext3格式化不全面。用blkid显示sda3是reiserfs的格式。
neilxp@neilxp-laptop:~$ blkid
/dev/sda1: UUID="883E-0E29" TYPE="vfat"
/dev/sda2: UUID="c36435d3-7b90-4b93-b1ca-7e610d2ade0b" TYPE="ext3"
/dev/sda3: UUID="d1a79b43-30b3-4195-91ee-e53f9fe356eb" TYPE="reiserfs"
/dev/sda5: UUID="499D-8EE2" TYPE="vfat"
/dev/sda6: UUID="29f345c6-c87b-4ef4-910b-c347e22f41ec" TYPE="ext3"
/dev/sda7: UUID="499D-8EE6" TYPE="vfat"
/dev/sda8: UUID="499D-8EE8" TYPE="vfat"
/dev/loop0: TYPE="squashfs"
用fdisk查看，sda3是83分区类型，推应ext3

这是我配置内核的部分选项，AHCI SATA已经选择了。

有什麽错误信息？

/boot 有啥东西？

/boot/grub/menu.lst 有何内容？

/boot on sda3, which was the partition of LFS
root@neilxp-laptop:~# ls /lfs/boot/ -R
/lfs/boot/:
config-2.6.27.4 grub lfskernel-2.6.27.4 System.map-2.6.27.4

/lfs/boot/grub:

i want to reuse my existing grub on sda2, which was brought by ubuntu host system.
its content:

最後一句 kernel panic 貌似是内核欠缺文件系统的支持引起的

ext3应该是默认就编译进内核的，否则系统都起不来啊。

内核中有无下面的配置项？
|----->SCSI low-level drivers
|---->Serial ATA (SATA) support
|---->intel PIIX/ICH SATA support

另，可参考：http://linuxman.blog.ccidnet.com/blo...id-280649.html

我使用的是linux-2.6.27.4的内核，其中配置选项中没有
|---->Serial ATA (SATA) support
|---->intel PIIX/ICH SATA support
有该如何办呢？
