I have googled this and found a thousand answers, but none of them seem to answer my problem.
I have been using the distro kernels (Mandriva), but needed to install a current kernel directly from kernel.org.
When doing a modprobe on some modules I get this error.
This error usually means that one thing is using a different version, but I can't find where that is happening.
I have a lot of kernels installed, but while the distro kernels don't give me that error, any kernel I install from source from Kernel.org, I get the error on a few modules.
