    ****************************************************************
    Quick detach and reattach of PCI functions for guest operating
    systems was found to cause occasional HTT001 and SIT002 abends
    which were the result of mishandled PCI function control blocks.
    

Problem conclusion

  • Code was added in these cases to either restore addressability
    to or check the validity of the control blocks.  This addressed
    the possible abend conditions.
