/usr/src/linux-source-3.4.4.tar.bz2 file and the .config file from /boot/config-3.4.4 ?
I am using: "make oldconfig; make all; make install; make modules_install"
Do I need to use the virtualbox-guest.tar.bz2 file ? How to use it with the kernel source tree ?

FYI, I am trying to recompile the kernel to get the oprofile.ko kernel module but
the kernel binaries are too different and the module does not load with the original kernel.
So I would need to change all the kernel modules + the kernel which I try to avoid
for obvious reasons. I just like to add the oprofile.ko kernel module to my custom
patch cloop so I can use it when needed.
Best Regards,

I think the kernel modules are "sensitive" to a few factors, gcc compiler version is one of them. Did you by any chance upgraded the gcc compiler version ? Since you only want to get the oprofile.ko, you might want to try to compile it inside a virtual machine, using the original DVD Live CD. In that case, hopefully you retained all the factors could cause the kernel module loader to fail the sanity check.
