No success. The Double Page Fault error still persist and all my  
development has seized due to the unstable environment.
When I display the TCB of the current thread it says:

Is seems to stop in the "loader pager". Can anybody give me pointers on  
what I can do at this point to get more information to help solve this  
problem.
