FWIW, I think this is where the problem occurred.  Probably tried 
to zero a page that didn't exist because of a failed KVA allocation.

I probably don't have my terminology correct since I'm a system 
admin and not a programmer (just a wannabe for the moment).  
The programmers on this list will likely correct me if I'm wrong.

We had several panics on one of our 4GB machines at the same 
point.  Our solution was to increase the KVA space to 2GB from 
1GB and rebuild the whole world with the new KVA setting.  The 
panics disappeared.
