    Exclamation [Resolved] VFS error with new kernel


    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/hda1 * 1 167 84136+ 6 FAT16
    /dev/hda2 168 428 131544 83 Linux

    Disk /dev/sda: 1031 MB, 1031798272 bytes
    64 heads, 32 sectors/track, 983 cylinders
    Units = cylinders of 2048 * 512 = 1048576 bytes

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

    ... so I will use this kernel.
