report uncorrectable bus error on Central Processing Unit (CPU) and uncorrectable error a software nmi has occurred on system on memory while performing excessive memory usage application or memory diagnostic. The error from the Integrated Management Module (IMM) chassis event log is as follows and results in a system restart. CHASSIS:(12/23/2014 02:23:11) An Uncorrectable Bus Error has occurred on bus CPUs. CHASSIS:(12/23/2014 02:23:01) Uncorrectable error detected for One of the DIMMs on Subsystem System Memory. The symptom can only be observed by the Three (3) DIMMs for One (1) CPU or Six (6) DIMMs for Two (2) CPUs ( One DIMM per channel ) configuration. Affected configurations The system may be any of the following IBM servers: System x3530 M4, type 7160 E5-xxxxV2, any model System x3630 M4, type 7158 E5-xxxxV2, any model This tip is not software specific. This tip is not option specific. The following system BIOS/UEFI level(s) are affected: UEFI version 1.60/1.70/1.71 are affected. Solution The issue has been addressed by the UEFI firmware code version 2.12 or later. The file is or will be available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and operating system on IBM Support's Fix Central web page, at the following URL: http://www.ibm.com/support/fixcentral/ Workaround This issue can be worked around by changing the UEFI setting to lower memory speed from default 1600 MT/s to 1333 MT/s. In UEFI setup menu, Select 'System Settings' --> 'Operating Modes' --> Choose Operating Mode: 'Custom Mode' --> Change Memory Speed to 'Balanced'. Additional information The system mistakenly triggers the failure symptom. The UEFI firmware will address this issue in next release.

firmware update from 28 revision to 34 revision could trigger error message 'An Uncorrectable Bus Error has occurred on bus CPUs' and cause system outage - IBM System x Applicable countries and regions Source RETAIN tip: H211442 Symptom Updating the Unified Extensible Firmware Interface (UEFI) firmware from revision 1.40 to any of these levels produces a CPU bus uncorrectable error, and causes the system to power down. UEFI firmware revision 1.50 UEFI firmware revision 1.51 UEFI firmware revision 1.60 UEFI https://www.ibm.com/support/entry/portal/docdisplay?lndocid=migr-5097080 firmware revision 1.70 The error is shown in the system event log (SEL) as: An Uncorrectable Bus Error has occurred on bus CPUs. The failure occurs only one time, and does not affect the system. This error is a false error. Affected configurations The system can be any of the following IBM servers: System x3500 https://www.ibm.com/support/entry/portal/docdisplay?lndocid=migr-5094109 M4, type 7383, any model System x3530 M4, type 7160, any model System x3550 M4, type 5459, any model System x3550 M4, type 7914, any model System x3630 M4, type 7158, any model System x3650 M4, type 7915, any model This tip is not software specific. This tip is not option specific. The following system BIOS/uEFI levels are affected: UEFI firmware revision 1.50 UEFI firmware revision 1.51 UEFI firmware revision 1.60 UEFI firmware revision 1.70 The system has the symptom described above. Solution The limitation statement will be updated in 2015 second quarter UEFI firmware code change history. Workaround AC power cycle the system to resolve the issue. Additional information The failure occurs only one time, and does not affect the system. This error is a false error.

Error Code = IMM events displayed by AMM (for example, Service Advisor, AMM web interface) Event ID = IMM events displayed by DSA diagnostic program (for example, in the Chassis Event https://publib.boulder.ibm.com/infocenter/bladectr/documentation/topic/com.ibm.bladecenter.hs23.doc/IMM_error_messages.html Log section) Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. See Parts listing to determine which components are consumable, structural, or CRU parts. If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained technician.
