Error description

  • PE54373-F002
    After applying PTF UK53738 for APAR PM06779 your CMAS may fail
    to initialize.  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 asid.
    .
    Additional Symptom(s) Search Keyword(s): init startup starting

    ****************************************************************
       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.
