just a simple question. What does the "Unable to handle kernel paging request at virtual address ..." usually indicate?

Does this mean a memory allocation problem, or just a memory addressing problem. Also, why does it come back with a virtual address and not a physical one? Does this mean it is doing something in user space?

I am writing a device driver for a Data Acquisition Card, but haven't got a clue what the bug in my code is.
