EYUXE0001I CPSM subsystem (EYUX) initialization complete EYUXE0023E ESSS address space not created - Invalid return code from EYU9X410 . Each time the CMAS is started and the failure occurs, it will leave an orphaned EYUX410 asid. . Additional Symptom(s) Search Keyword(s): init startup starting KIXREVPAD

The following messages will be * * received: * * . * * EYUXE0001I CPSM subsystem (EYUX) * * initialization complete * * EYUXE0023E ESSS address space not * * created - Invalid return * * code from EYU9X410 * * . * * Each time the CMAS is started and * * the failure occurs, it will leave an * * orphaned EYUX410 address space. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, CMASes which failed to initialize * * must be restarted from an SEYUAUTH library * * which contains this fix. Note that the * * restarts do not need to be done at the same * * time. * * . * * An IPL is not required to implement the fix * * but might be indicated to clean up orphaned * * EYUX410 address spaces. * **************************************************************** The fix for APAR PM06779 changed the CMAS bootstrap program EYU9XECS to examine the ESSS System Address Space Block (XESS) to determine whether the EYUX410 address space initialized, after POSTing the ESSS initialization program with the address of the XESS and WAITing for ESSS initialization to complete. The branch entry to the cross-memory POST does not restore the contents of all registers before returning to EYU9XECS, causing unpredictable results if the base register for the XESS is changed. If the XESS base is not valid, EYU9XECS might assume that EYUX410 initialization failed, terminate the CMAS, and at- tempt to clean up, orphaning the EYUX410 address space.
Problem conclusion
EYU9XECS was modified to restore the XESS base register from the ESSS Release Vector element on return from POSTing the ESSS initialization program.
