A page fault panic occurs when you try to access memory which is not valid.
Why not post the rest of the panic log? That's the information that
tells you what really happened.
In particular, on Intel, the CR2 register contains the address which
caused the panic. You can draw certain conclusions from the type of
value found in CR2.
There are too many potential causes to classify this further based on
insufficient evidence.
