The schedule looks fine.

You can fill uninitialised values with nans.  This is easier to  
detect than large value.

You can output the grid structure and see where Carpet copies.  Try  
Carpet::verbose, maybe Carpet::veryverbose, and also  
CarpetLib::output_bboxes.  Then (a) evaluate the RHS on the initial  
data without performing any time steps, and (b) take a single time  
step with the Euler method.  This leads to results that are easier to  
interpret.

In case Wolfgang is right with his suspicion, you can also try to set  
the spatial order to 3 again.
