With my kernel and with a Generic kernel, I am getting a Fatal trap 12 
when trying to access the network.  
The first thing that happens on the network seems to cause the panic. 
 The following was an error with a
generic kernel.  I'm typing it so there could be mistakes.

Fatal trap 12: page fault while in kernel mode
fault virtual address    = 0x0
fault code                    = supervisor read, page not present

The debugger is open but I don't know what I'm looking for.  Any help 
will be appreciated.

Thanks,
