Issue Description: 

In an extremely limited number of applications, and with a single system
configuration, the Sun Fire V440 or Netra 440 system may experience an 
unexpected reset and will reboot.

The specific configuration which triggers this situation is as follows:

   Some or all of the data being transferred is transported via the first
   onboard ethernet interface "ce0" (Cassini ASIC).
   
When this issue occurs, the system will reset and an error message appears
on the console.  The system then reboots.  No core files are generated 
and the reset output will not be logged to the /var/adm/messages file.

At system reset, the error message displayed on the console is:

      Fatal Error Reset   
      SC Alert: Host System has Reset

If it is suspected that the V440 is experiencing this issue, change the OBP 
variables as follows to provide more verbose output on the next failure.  

Note: The settings below are only recommended to verify whether the system is 
experiencing this issue and should not be used long term.  Once the failure is 
verified then the parameters should be set back to the recommended (error-reset, 
power-on-reset) settings.  These settings are recommended so that the output 
will be verbose, but the ALOM 64k circular buffer will not get overrun by POST
and Obdiag messages and lose the intended FATAL RESET output.

     diag-switch?    true
     post-trigger    none
     obdiag-trigger  none

When the parameters above are set, the error message will include some 
additional information indicating the reset reason as "PBM FATAL", with a 
PCI IO-Bridge register output similar to:

   ha019 console login:

   Fatal Error Reset
   SC Alert: Host System has Reset

This issue could occur when high activity on the ce0 interface, coupled with 
JBUS activity, generates an error on one of the JBUS control lines.
The error condition that causes this situation is extremely rare and is
configuration specific.

There is currently no permanent resolution.  Customer sites experiencing this
issue should use the workaround procedures provided below.

Implementation: 

---
        |   |   MANDATORY (Fully Proactive)
         ---    
         
  
         ---
        |   |   CONTROLLED PROACTIVE (per Sun Geo Plan) 
         --- 
         
                                
         ---
        | X |   REACTIVE (As Required)
         ---

Corrective Action: 

The following recommendation is provided as a guideline for authorized
Sun Services Field Representatives who may encounter the above
mentioned issue.

A long-term corrective action plan is being developed by Sun and will be
delivered via Sun's service team.   In the meantime, utilize the following
workarounds.  These workarounds require some configuration changes.

The first "ce0" (net0) onboard interface should not be used.  To replace the 
functionality of this interface, use either of the following:

a) Use only the second "ce1" (net1) onboard network interface.  

    OR

b) Install a PCI ethernet card in any available PCI slot.  Choosing to place 
the card into a 33MHz slot may lower performance relative to using the card
in a 66MHz slot.

The following Sun card is tested and supported as a workaround for full 
gigabit network replacement functionality:

    X1150A     501-5902-xx Sun GigaSwift Ethernet UTP (Copper)

The following Sun card is tested and supported, but will not provide gigabit
network functionality equivalent to the onboard port:

    X2222A     501-5727-xx Dual Ultra-2 SCSI/Dual FastEthernet PCI Adapter


Additional Procedures:

It is highly recommended that to ensure the "ce0" (net0) is never accessed
inadvertantly in a matter that could trigger this issue (e.g. SunVTS),
that the "ce0" interface be completely disabled.  It is also recommended 
due to Solaris instance numbering, that this be done after initial Solaris 
installation, to ensure net1 is assigned "ce1" instance, instead of "ce0".

To completely disable "ce0" (net0) from the system, use the following 
commands to install an NVRAM script at the OBP "ok" prompt:
1. ok nvedit
2.   0: probe-all install-console banner 
3.   1: " /pci@1c,600000/network@2" $delete-device drop 
4.   2: 
   Type "Ctrl-C" to exit nvedit.
5. ok nvstore
6. ok setenv use-nvramrc? true 
   use-nvramrc? =        true
7. ok reset-all

After the system resets, "ce0" should not be visible by OBP (i.e. you should 
not see a path to "ce0" [/pci@1c,600000/network@2] when you run "show-devs" 
from OBP).  ce0 device should not be seen by Solaris (i.e. prtconf or prtpicl).

Comments: 

None. 


============================================================================

Implementation Footnote: 

i)   In case of MANDATORY FINs, Sun Services will attempt to    
     contact all affected customers to recommend implementation of 
     the FIN. 
   
ii)  For CONTROLLED PROACTIVE FINs, Sun 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, Sun Services will implement the FIN as the   
     need arises.
