You are passing a pointer-to-pointer-to-character (char **) as the first argument to copy_from_user, but you should be passing char * instead. So ditch the ampersand, and all will be right with the world! I could give you a thorough explanation of why this is failing, if you like, but to make a long story short, this line of code is smashing the stack! I'm always happy to help. -- Chris
