              Tuning the ecache_scan_rate parameter of the Solaris 
                cache scrubber provides improved Ecache parity error protection 
                on non-mirrored SRAM UltraSPARC II-based systems (FIN  I0755-1).  
         
           
         
        - 
          
            Any Fatal Reset errors in the UE 3X00 to UE 6X00 
              servers should be evaluated to determined whether it is because 
              of Ecache Tag error. Do not assume that a Fatal Reset error implies 
              that the system board is defective (FIN  I0587-1).  
           
         
        -  
          
The current diagnostic procedure to identify the faulty 
            CPU module from CPU Ecache parity errors is flawed, and it could easily 
            lead to the wrong CPU being replaced (FIN  I0570-3).

Failure to handle CPU Modules correctly can result 
            in physical damage; proper torquing techniques are required (FIN  I0403-2). 
            
         
        - Booting from the network can fail with Solaris 2.5.1 and Solaris 2.6 
          when using 464MHz or faster processors (FIN I0707-1).
