Impact
Contributing Factors AMD has informed Sun about an issue [1] that may occur in a limited number of single-core AMD Opteron(TM) x52 (2.6 GHz) and x54 (2.8 GHz) microprocessors. AMD reports that a small number of these processors manufactured in 2005 and early 2006 have been observed to produce inconsistent results in a non-production test environment with the convergence of the following three simultaneous conditions:
AMD has informed us that this issue was not observed by them on AMD Opteron x52 and x54 systems running commercially available applications, including Web servers, application servers, transaction processing servers, database servers or file print servers. [1] For a technical description of the AMD Opteron Processor issue please see AMD's web site per the below URL; http://www.amd.com/opteron/productionnotice AMD asserts that should the described issue occur, there will be no indications that the Opteron processor has produced inconsistent results. Symptoms This issue may occur only on the following Sun platforms:
Notes:
A Question and Answer document has been developed as a guideline for all customer communications, and is available via the below URL; http://sdpsweb.central.sun.com/FIN_FCO/FCO/A0269-1/SPE/Q&A.pdf AMD has created a processor verification software tool that can be used to identify potentially implicated parts (by lowering the core voltage in the system). AMD has a standalone version that boots into the OS diagnostics kernel and runs for 15 minutes per CPU (and can run in parallel across multiple CPUs). The software verification tool must be run in order for the suspect units to be flagged. Only the processor verification software tool can determine for sure which parts are actually functional. IMPORTANT: The diagnostic tool must only be run by trained service personnel and only run once on the target systems. On no account must the diagnostic tools be given to customers to run or re-run tests. SPECIAL CONSIDERATIONS: There will be no charge to customers for any onsite activities related to this Field Information Notice. Root Cause
Workaround A Field Change Order will be released shortly providing for material to allow for the replacement of any processors that fail the processor verification software tool. This FCO is scheduled to release in early May of 2006. In the meantime: 1. When a customer calls the call center, they should be routed to the field. The field team will give the customer details on mode and manifestation, then Sun and the customer will determine a remediation plan as necessary. NOTE: Refer to the Question and Answer document in the Issue Description section linked above. 2. If the customer requires remediation, the field will schedule time to run processor verification software tool in order to identify suspect processors. The processor verification software tool can be obtained from the below URL; http://sdpsweb.central.sun.com/FIN_FCO/FCO/A0269-1/SPE/Tools/ Important! The Live CD is set up to use 250 IPs on the 192.168.150.0 class C subnet. Please discuss this with the customer when planning to use the LiveCD so that they can determine if this range of IP addresses will cause any conflict on their subnet. Should any conflict be found you may contact PTS for further assistance. The AMD Processor Verification Tool User Guide can be found in the above directory or directly from the below URL; Note: Files in pdf format may require you to save the file and open it locally. A Procedures document has been provided to aid you in the use of the verification tool, and can be found via the below URL; http://sdpsweb.central.sun.com/FIN_FCO/FCO/A0269-1/SPE/Opteron_Screen_Procedure_rev_1_0.sxw In addition, a Transfer of Information (TOI) has been developed and provided by PTS via the below URL; http://sdpsweb.central.sun.com/FIN_FCO/FCO/A0269-1/SPE/PTS-TOI.pdf Note: The running of this verification tool requires the system be powered down.
