Insmod does not work because an unknown character in the module

Question

When I do an insmod of a Kernel object. This fails due to some unknown characters in this module.

But for some reason, He does not show me symbols (which he speaks as unknown).

Anyway, to find this? Please inform.

Answer 1

This can happen if your linux kernel and your modules have a mismatch. Cases like you do insmod to a different version of the kernel than the one you created for the module.

Make sure that you are using the version of the kernel on which your module is created. I assume that you used the wrong version of the kernel headers. Try changing this.
