A patch for fixing this problem
when adding a default route, RHEL5.1 kernel regards this action as a special case.
when this scenario happens, kernel doesn't update the round-robin
point(fn->rr_ptr) of the root fib node(fn->rr_ptr).
So It fails when lookup the default route.
This bug has been fixed in the latest kernel.
