What happens if you ignore this warning?
AFAIK, this is used to enforce strict checking of version match between kernel modules and the kernel image itself e.g you can not normally load module compiled for 2.6.30 on 2.6.29 kernel. I don't know about the details, but I guess module.symvers holds some information which will embedded into final form of kernel modules. -- regards, Mulyadi Santosa Freelance Linux trainer blog: the-hydra.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
