Hi,
I am getting some problem in inserting a module even after compiling it for the running kernel.
[root@localhost kernel-modules]# insmod hello-1.ko
insmod: error inserting 'hello-1.ko': -1 Invalid module format
[root@localhost kernel-modules]#
This does not seem to be related with the common vermagic problem, as I see the following message in dmesg.
hello_1: disagrees about version of symbol struct_module
It looks like a modversions problem. The kernel which you are using seems

Please see the Makefile and make output below. Please clarify me what goes wrong.

obj-m += hello-1.o
