problem of load kernel after uncompressiong kernel Image .... (linuxppc 2.4.27)

[FLAMENT David]

Dear,
 
    Here is my problems,

    OS: kernel 2.4.27 linuxppc-embedded
    platform: ppc rattler 8248
 
    When I load a kernel image (uImage) with u-boot, the prompt of kernel is blocking
    
    boot args kernel parameters : 
        "console=ttyS0,38400n8 nfsroot=/tftpboot/ppc_root rw ip=192.168.1.23:192.168.1.21::::eth0:off"
 
the screenshot of loading kernel :
    TFTP from server 192.168.1.21; our IP address is 192.168.1.23
    Filename 'uImage'.
    Load address: 0x100000
    Loading: #################################################################
    #################################################################
    ############################
    done
    Bytes transferred = 803951 (c446f hex)
    ## Booting image at 00100000 ...
    Image Name: Linux-2.4.27-pre1
    Image Type: PowerPC Linux Kernel Image (gzip compressed)
    Data Size: 803887 Bytes = 785 kB
    Load Address: 00000000
    Entry Point: 00000000
    Verifying Checksum ... OK
    Uncompressing Kernel Image ... OK
 
You can see, after uncompressing kernel, there are nothing !!! 
I try to use another kernel 2.4.26 with the same nfsroot and boot parameters and I can ping my target but not with linuxppc 2.4.27.
If you have an idea about this problem !! thank's.
note : I use a rattler 8248 with a 2.4.27 linuxppc kernel
 
Help me please !!!
