Hello,
Thank you very much for your reply.
This is exactly what I did: boot the DVD iso within a virtual machine without any update nor modification.
It worked with some previous Knoppix releases but not 7.0.3. It suppose that Klaus did not compile the
Knoppix kernels from Knoppix, reason for the version mismatch probably created by a different gcc version.
I guess it will help to find out which version of gcc has been used to compile the 703 kernel.
Best Regards,
Gilles

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.
