You need a newer version of modutils

Try module-init-tools-3.0.tar.gz from
http://www.kernel.org/pub/linux/kernel/people/rusty/modules/

This fixed that problem for me on 2.6.3 and 2.6.5 on a 8266. The other
version is known not to work with the new module initialization stuff in
the 2.6 kernels.

Hi,,,
So so... sorry. I need to your process of module-init-tools-3.0 upgrade in detail.
Unfortunately, when i upgrade module-init-tools-3.0, I have a troble with module insert continuously.
Firstly, my test environment...

1) target : ppc8260 custom board.
2) kernel has compiled with module support
3) using kernel 2.6.5(also 2.6.3, 2.6.4)
4) using modutils 2.4.22
5) ELDK 3.0( cross compiler, NFS)

Following test message....

After booting of kernel 2.6.5..

bash-2.05b# ls
Makefile  Makefile.l  hello.c  hello.ko  hello.mod.c  hello.mod.o  hello.o
==> I  had to compile the modules using the recommended way of 2.6.x
( $(MAKE) -C /kernel_path CROSS_COMPILE=xx_xx SUBDIRS=$(PWD) modules)

bash-2.05b# insmod hello.ko
insmod: QM_MODULES: Function not implemented

bash-2.05b# depmod -V
depmod version 2.4.22
depmod: QM_MODULES: Function not implemented

I got to "module-init-tools-3.0.tar.gz'
After installing, boot process message is...

VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 76k init
request_module: runaway loop modprobe binfmt-4c46
request_module: runaway loop modprobe binfmt-4c46
request_module: runaway loop modprobe binfmt-4c46
request_module: runaway loop modprobe binfmt-4c46
request_module: runaway loop modprobe binfmt-4c46

Here stopped.

As you can see above, what's the reason of above error?
Any help would be appreciated.

Call me "Lone".
Thanks,

Oh, and... You will have to recompile the modules using the recommended
way for 2.6
(eg 'make -C /path/to/linux/ SUBDIRS=$PWD modules') and use the .ko
object files.

There are also some other changes in the module layout.
(see http://lwn.net/Articles/driver-porting/ for more info )

Problems of kernel-2.6.4 for mpc8260

[김치환]

I got succeeded to port kernel 2.6.4 to out custom MPC8260 board with
the help of DENX ELDK 3.0 tool. Thanks!! But there is some problems to
be solved.

After booting, when I try to install module, following error occured.

      bash-2.05b# insmod dsrc_drv.o
      insmod: QM_MODULES: Function not implemented

      bash-2.05b# insmod -V
      insmod version 2.4.22

As you can see above, the version of modutils seems to be fine. right?
If so, what's the reason of above error? And one more problem. At boot
sequence(as following) lots of unexpected 'modprobe: xxx' messages are
issued.

How can I fix these problems?

Module support seems not to be enabled in your kernel.

See above. Furthermore the module dependency file may not be correct for
your arch.
