Issue Description: 
From FIN# I0331-1
 
Depending on system configuration and the value for the system
parameter "dr-max-mem", a domain can become unbootable if OBP runs out
of its own memory and goes into UFSBOOT text/data space.  The result is
UFSBOOT crashes.  Typically, this occurs when the value for
"dr-max-mem" is 16 GB.


Below are two examples of the failure:

Corrective Action: 
*Addition for FIN# I0505-2;
 
Install Patch-ID# 104853-02 or higher on the SSP associated with
the E10K domain, making sure to follow the installation instructions 
associated with the patch.  If SSP is version 3.1 or higher, this 
patch does not apply.
Comments: 
--------------------------------------------------------------------------
Implementation Footnote:

i)   In case of MANDATORY FINs, Enterprise Services will attempt to    
     contact all affected customers to recommend implementation of 
     the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical    
     support teams will recommend implementation of the FIN  (to their  
     respective accounts), at the convenience of the customer. 

iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the   
     need arises.
