What is different between them? Zimage seems to be same, but uInitrd is not.
If Ubuntu just had exactly same kernel (without these errors) what is in Debian, I would be happy. Is it possible to compile Ubuntu kernel with the same settings Debian has now?
Or is there something else I don't understand?
