As I understand the problem, this will not help me as the CPU itself is 
on hold waiting for the assembly line to complete. It may give me enough 
to spot the faulty situation and crash the system... but I am aiming for 
an Enterprise grade product.  Crash/oops is not something I want to put 
into the system if I do not absolutely have to and I do have a hardware 
watch-dog that will pull me out if I do.

So just for the fun of it I am going to follow up on this PEX_ERR_DISR, 
but I do not see how it will help.
