Issue Description: 

Customers who receive a Sun Fire V480 or V880 system configured with
Micron DIMMs may experience POST failures.  These failures can show up
as DOAs, since they occur at power-up.

The POST failure message usually contains 'probe and Setup memory'.

During the POST process, the  CPU is typically the initial indictment.
This occurs as the failure message will indicate a certain DIMM
location, prompting the Technician to replace the reported DIMM.  After
doing so, the CPU will still fail.  DIMMs that are removed from this
failing CPU will often pass when tested in another system.

Conversely, when a new set of DIMMs is installed in the original CPU,
the CPU will then pass as well.  This typically occurs when a vendor
other than Micron is installed in the CPU.

Failures are due to the DRAM DQs firing incorrectly, causing data
contention.This causes a boot fail because the data bus is shared with
other DRAM. The DQs are firing due to the Micron DRAM seeing an
"illegal" LMR (Load Mode Register used for initialization).

Additionally aggravating the issue, a clock pulse is caused by floating
inputs to the PLL on the module. This unique condition puts the Micron
DRAM into a "reserved" mode.

NOTE: FIN Tracking Instructions for Radiance/SPWeb:
--------------------------------------------------

If a Radiance case involves the application of a FIN to solve a customer
issue, please complete the following steps in Radiance/SPWeb prior to
closing the case:

    o Select "Field Information Notice" in the REFERENCE TYPE field.

    o Enter FIN ID number in the REFERENCE ID field.
      For example; I1111-1.

If possible, include additional details in the REFERENCE SUMMARY field
(ie. implementation complete, customer declined, etc.)

Implementation Notes:
--------------------

In case of "Mandatory" FINs, Sun Services will attempt to contact
all known customers to recommend proactive implementation.

For "Controlled Proactive" FINs, Sun Services mission critical
support teams will initiate proactive implementation efforts for
their respective accounts as required.

For "Reactive" FINs, Sun Services and partners will implement
the necessary corrective actions as the need arises.
