LFS 6.3 Kernel panic - not syncing:VFS: Unable to mount root

[wyylling]

VFS:Unable to mount root fs via NFS,trying floppy
VFS:Cannot open root device "sda10" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partions:

Kernel panic - not syncing:VFS: Unable to mount root fs on unknown-block(2,0)

The harddisk layout is :

/dev/sda1 * .... HPFS/NTFS
/dev/sda2 .... W95 Ext'd(LBA)
/dev/sda5 .... HPFS/NTFS
/dev/sda6 .... HPFS/NTFS
/dev/sda7 * .... Linux
/dev/sda8 .... Linux swap/Solaris
/dev/sda9 .... Linux
/dev/sda10 .... Linux
My LFS is installed in the /dev/sda10

The grub/menu.lst is:

title Gentoo Linux 2.6
root (hd0,6)
kernel /boot/kernel-genkernel root=/dev/ram0 real_root=/dev/sda9
initrd /boot/initramfs-genkernel

title LFS 6.3
root (hd0,9)
kernel /boot/lfskernel-2.6.22.5 root=/dev/sda10
in the LFS' /boot:System.map-2.6.22.5 lfskernel-2.6.22.5

1 sata驱动
2 文件系统模块
fstab
都要配置正确才好

貌似2.6.18（记不清具体版本）之后已经不分ide和sata和scsi，全当成scsi对待了（不过相应模块还是需要的）...

如果你的是ide硬盘，还是要把scsi编译进去，而可以不要ide那部分...

代码： 全选

[hunt@bubble ~/hunt's/source/rc]$ O_< grep IDE 2.6.26.3.config 
CONFIG_HAVE_IDE=y
# CONFIG_IDE is not set
[hunt@bubble ~/hunt's/source/rc]$ O_< grep SCSI 2.6.26.3.config 
# SCSI device support
CONFIG_SCSI=y
CONFIG_SCSI_DMA=y

当然这样子也是可以启动了，把sda10换成hda10貌似就可以了...

我的ide硬盘，如下：
