Set a breakpoint on the interrupt handler.  Check the value of SS.
You may find that the problem is that your interrupt handler is
executing in one of DOS' stacks rather than your stack.  If this is
the case, the call to the NFS library may cause DOS' stack to
overflow.  If this is your problem, then the solution is to switch to
your application's stack on entry to your interrupt handler and the
restore the previous stack before exiting from the interrupt handler.
