no access to kernel symbols

[Stephan Ruettiger (r0337c)]

Hello all,

i have big problems to access the symbols from the kernel. The mystique
is, that i can see all the symblols with:

# cat /proc/ksyms
c000283c clear_page_Rc0b2879e
c0005d78 do_signal_R6b4b6273
c0007d80 syscall_trace_R8994abdd
c0002000 transfer_to_handler_R90501868
c0002544 int_return_Rb0f19035
.........

also i see it with:

#ksyms -a
Address  Symbol         Defined by
C000283C clear_page_Rc0b2879e
C0005D78 do_signal_R6b4b6273
C0007D80 syscall_trace_R8994abdd
C0002000 transfer_to_handler_R90501868
C0002544 int_return_Rb0f19035
........

But this doesn't work:

# insmod -fv hello

textseg = 0x18537f8
bss_size = 25508080
last byte = 0x18548f0
module size = 4344
jump table = 0x18538f0
versioned kernel: no
versioned module: no
ELF kernel
ELF module
printk undefined
Loading failed! The module symbols (from linux-2.2.13) don't match your
linux-2.2.13

With objdump i verify that all, the kernel, the hello module and the
insmod programm are all of the elf32-powerpc format. I compiled the
hello.c with the flags -c -Wall -DMODULE -D__KERNEL__ on the target
board (MBX860,NFS,egcs-2.92.33) with the same include files i used to
compile the kernel 2.2.13.

My hello.c file :
-------------------------------------------
#define __KERNEL__
#define MODULE
#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/version.h>

char kernel_version[] = UTS_RELEASE;

int init_module(void)
{
  printk("<1> Hello, world\n");
  return 0;
}
void cleanup_module(void)
{
  printk("<1> Goodbye cruel world\n");
}
--------------------------------------------


If anyone have any suggestion, please send me. I don't have no more
ideas for the moment.
