It makes it hard to follow the conversation. :) 2) In your first post above you ask for help "as early as possible". That's a no no also. :) 3) And finally if you really want help try posting the output you are seeing when you try loading the module. The more information you provide the better the chance someone will be able/willing to help you. :) -- kr -- Kernelnewbies: Help each other learn about the Linux kernel.
