I tried this one on the gurus themselves - known bug.  I'm getting the
ridiculous output on my database server and also on another system. 
When I close down the application on the second system the figures all
make sense.

There is a known bug in the computation of pp_kernel on systems using
Oracle and shared memory. I think that's the deal. pp_kernel will be
reported absurdly high.
