Page_fault_in_nonpaged_area

Hi Redbatman,

To answer your question directly, it basically means that the kernel attempted to access a memory address which was not valid which isn't allowed.

Code:

5: kd> .trap 0xffffa685194280d0
NOTE: The trap frame does not contain all registers.
Some register values may be zeroed or incorrect.
