I have linux installed in vmware which is not connected to net and so I have to manually download the source.

---------- Post updated 02-03-12 at 01:03 PM ---------- Previous update was 02-02-12 at 08:56 PM ----------

Now I have open suse kernel kernel 3.1.0-1.2-desktop and its kernel source.

Again the module gets built.
While loading a kernel module I am getting Invalid module format error with description "first_driver: no symbol version for module_layout"

The following are the logs:

Code:

linux-k2kj:/home/rkpsuse/Emertxe/CourseTemplates/FirstDriver # insmod first_driver.ko 
insmod: error inserting 'first_driver.ko': -1 Invalid module format

linux-k2kj:/home/rkpsuse/Emertxe/CourseTemplates/FirstDriver # modinfo first_driver.ko 
filename:       first_driver.ko
description:    My First Driver
author:         Emertxe Info. Tech
license:        GPL
srcversion:     C4CCFC5DA59927FA4A479E6
depends:        
vermagic:       3.1.0-1.2-desktop SMP preempt mod_unload modversions 686 

linux-k2kj:/home/rkpsuse/Emertxe/CourseTemplates/FirstDriver # dmesg | tail
[ 8797.391736] first_driver: no symbol version for module_layout

linux-k2kj:/home/rkpsuse/Emertxe/CourseTemplates/FirstDriver # uname -r
3.1.0-1.2-desktop

FYI I have compiled the kernel as follows:
Make mrprpoper
make menuconfig
Make
Make modules
Make modules_install
Make install

Am I missing something?
How to resolve this issue?

moduload

moduload(2)							System Calls Manual						       moduload(2)

NAME

       moduload - unload a kernel module on demand

SYNOPSIS

DESCRIPTION

       allows processes with appropriate privilege to demand unload one or all unloadable modules from the running kernel.  A module is considered
       unloadable if it is not currently in use, if no module depending on it is currently loaded, and if  the	module	is  not  being	loaded	or
       unloaded  from  the  kernel.   If module_id is set to 0 (zero), attempts to unload all unloadable modules, otherwise attempts to unload the
       module specified by module_id.

   Notes
       is currently implemented as a macro.

   Security Restrictions
       is restricted to superuser processes or privileged processes.  A privileged process requires the privilege to execute the system call.

       See privileges(5), for more information about the privilege.

RETURN VALUE

       On success, returns 0, otherwise it returns -1 and sets to indicate the error.

ERRORS

       fails if one or more of the following are true:

	      module_id     does not correspond to any valid currently loaded kernel module.

	      The caller is not a superuser process or a privileged process.

	      There are outstanding references to the module, or modules that depend
			    on this module are currently loaded, or profiling is enabled, or the module is in  the  process  of  being	loaded	or
			    unloaded from the kernel.

	      The Dynamically Loadable Kernel Module feature is not initialized.
