HIPER (High Impact and/or Pervasive)
Abstract
The HIPER description was revised to remove SMT4 as a mitigation. IBM has determined that SMT4 will not fully prevent the issue.
HIPER/Pervasive: A problem was fixed for an issue attempting to recover from a processor core error. The failed recovery escalates to either a system checkstop or a processor core hang. The system checkstop is reported with SRC B113E504 or B181E540. The processor core hang has been observed as a partition hang and SRC B200F007 is reported when the partition fails to shutdown. The issue may also result in a partition crash or HMC Incomplete. With this fix, the processor core recovery will work correctly with no effect on the system.
