Use "rpm -Vf /path/to/original/module.ko"

If rpm tells you that the checksum has been modified, then the
"original" file you've got isn't the correct file.  Download the rpm
that owns that file, and use "rpm -i --replacefiles --replacepkgs
" to reinstall the kernel package.

Thank you Gordon,

I downloaded the original .rpm and extracted the files that I had 
changed during my testing and replaced them on the system. Its working now.


Strange, as all I had done was copy the relevant .ko's elsewhere for 
safekeeping while I was testing and the fault arose when I coped them 
back. Weird.


Thanks

Ken

Not sure if i understand your problem. Try to regenerate the map

Hi Leon, I tried that and get the same error. Its to do with the 
modules being signed. But I don't see how I have changed anything to 
do with that - unless I'm missing some subtle detail.

Any ideas folks?

Thanks
