Explanation: There was a failure most likely attributable to a memory DIMM (or DIMMs), but it could also be software-related or require further support.
Impact: Availability Severity: SPE
System firmware changes that affect all systems
HIPER/Non-Pervasive: DEFERRED: A problem was fixed that caused a system crash with SRC B170E540.
HIPER/Non-Pervasive: A related problem was also fixed that could cause a live lock on the power bus resulting in a system crash.
DEFERRED: A problem was fixed that caused an uncorrectable error (SRC B123E504) to be erroneously logged when 64GB DIMMs were installed in a system that already had 16GB or 32GB DIMMs.
To address poor placement of partitions following a reboot of a server with unlicensed cores, the firmware was enhanced to run the affinity manager when the initialize configuration operation is done from the HMC. A problem was also fixed that caused the hypervisor to be left in an inconsistent state after a partition create operation failed.
Concurrent hot add/repair maintenance firmware fixes
A problem was fixed that caused a CHARM operation to fail after this sequence of events:
1. User-initiated platform system dump is requested (from ASMI or HMC).
2. Service processor reset/reload takes place while dump collection is in progress.
3. User attempts a CHARM operation.
