It means that you've got a bad pointer in your code.

Exactly the same thing it would mean if you got a "SEGV" in a Linux program, or a GPF in a Windows program. Except that pointer errors in kernel drivers tend to crash your OS on you ;-)

As far as an "EXAMPLE !!!!" - it sounds like you've got one or two good examples right in your code.

As far as what to do about it, I'd recommend both of these books:

Linux Device Drivers, 3rd Ed:

Linux Kernel Development, 2nd Ed:
