VFS error with new kernel

[Seb26]

Hi

I've got a problem ( as you can imagine )

So ... I'm using a Kubuntu PC (as linux dev) with also Windows XP ( dual boot )

I want to update the kernel of my x86 embeded board to enable the framebuffer, I will need it for dev.

The board : ICOP VSX-6154 : >> HERE <<

On this board, I've restore X-Linux 5.51 ( ICOP Linux distribution ) on flash disk ( using GHOST + image provided by ICOP ) ...

This installation works fine, exept framebuffer is disabled on it ...

The X-Linux v5.51 overview : >> HERE <<

The working system in 2 words :

2 partitions on the disk :

> hda1 = MS DOS (bootable) with syslinux.
> hda2 = Linux ( ID=83) with all data that are OK with original kernel

The SYSLINUX.CFG (/hda1/) contain :

DEFAULT linux

LABEL linux
KERNEL linux
APPEND root=/dev/hda2

The story in 2 words :

I've take the .config from the working Linux, download last full sources from kernel.org ( v2.6.28 ) , then I updates my .config and set all default values for all (NEW) options.

Then build the new kernel.

After that, I've take the generated bzImage from /arch/x86/ and put it on my flash disk as kernel image loaded by SysLinux.

But the boot fails on VFS :

BootError.jpg

It looks like the kernel cannot mount /dev/hda2 as / ...

Does this mean that the filesystem ( Linux 83 ) is not accepted by my new kernel, or is that mean the data in hda2 aren't good ?

Note : when I restore the original kernel, the mount is OK, so the partition is not corrupted I think ...

Thanks for any idea.

If that can help, here is the fdisk -l result :

Disk /dev/hda: 1024 MB, 1024966656 bytes
16 heads, 63 sectors/track, 1986 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System

/dev/hda2 168 428 131544 83 Linux

Disk /dev/sda: 1031 MB, 1031798272 bytes

I've try with previous sources (version 2.6.24.7) and all is OK now

... so I will use this kernel.

Bye.
