It means what it says. You have a pointer that is not initialised, or is 
initialised to zero, and it is being dereferenced. Could be just about 
anything, although the most common error is to forget to kmalloc a structure, 
and then reference an element.

You can figure out where the problem is by running this through a program 
called ksymoops, which turns these stack variables back into a call trace. 
You _must_ do this yourself, with a System.map file that matches your kernel 
compile.
