    14680 New error detection function
    13489 z/OS is using a VMAC and linux is using the burned in mac,
    ignoring the high order byte.
    15214 ABEND0C4 ISTSRRIE -  PCIe Data Load/Store commands
    received CC2 when ringing EQ doorbell.  Routine PCI_Error was
    recording a TSNS VIT entry in while running disabled. An
    ABEND0C4 occured trying to save registers in the RPH which did
    not exists.
    ABEND0A9 FF14 ISTSRRCL - PCIe Data Load/Store commands received
    CC2 causing error path logic to execute.  New code to read
    internal errror buffer caused savearea requirements in module
    calling sequence to exceed the CRA size during CLOSE processing.
    
    15107 Interface fails to activate with message: EZZ4336I ERROR
    DURING ACTIVATION OF INTERFACE EZARIUT10001 - CODE 8010514B
    DIAGNOSTIC CODE 02
    14563 Access registers in ISTORCDG were not cleared before a
    base register is used to access DSDCB control block. This caused
    the program check to access the value from the DSDCB.
    14863 ISTRAFT1 received control to format traces entries and
    found several unknown traces entries.
    12866 When a TCPIP stack using Syplexports or IPSEC for
    Distributed DVIPA is stopped and restarted, but the associated
    VTAM is not restarted, VTAM will not reconnect to the Coupling
    Facility structures EZBEPORT  or EZBDVIPA.
    13342 A major node was activated that had a PUTYPE coded on a PU
    statement.  A ZAD error was detected in ISTSD4VC which assumed
    the RNCGP was nonzero.
    14038 When the stack cleans up an alternate link, it is doing so
    without sending a Delete Link LLC signal.
    15236 When global inopdump is specified with F NET,INOPDUMP=ON,
    if an Adapter goes inoperative, an INOPDUMP is not taken.
    15242 Anchor pool cell block failures because of contention
    issues when the cell pool block was allocated.
    

Problem conclusion

  • 14680 Add error detection.
    13489 Turn "u" bit off in the GID generation
    15214 ABEND0A9 FF14 ISTSRRCL - ISTAPCKU, ISTSRCAS and ISTSRIDD
    have been modified to increased CRA sizes to accomodate the
    increased code path.
    ABEND0C4 ISTSRRIE -ISTZMAC(IPCI_Error) - Modified trace
    invocation to avoid saving registers in RPH since one is not
    available in PCI interrupt (disabled) code path.
    15107 The device driver has been modified to wait for the port
    to become active asynchronously. When the partner TCP/IP stack
    and interface activate, an asynchronous event will notify the
    local stack the port is now available.
    14563 Declare register 3 for DSDCB address and restricted reg3.
    Compiler will not load access reg3.
    14863 RAFTVIT has been changed to recognized all known VIT trace
    records.
    12866 VTAM was modfied to allow TCPIP to reconnect to a Coupling
    Facility structure after TCPIP has been restarted
    13342 ISTSD4VC has been updated to check for RNCGP nonzero
    before checking RGPLNCA.
    14038 Send a Delete Link LLC signal with reason code 00050000
    when cleaning up an alternate link.  Made other corrections to
    LLC signal logic to conform to design.
    15236 We were resetting the INOPDUMP indicator in the NCB on
    adapter initialization. Modified to initialize all INOP
    indicators except the INOPDUMP indicator.
    15242 Anchor pool cell block logic was changed to detect CDS
    contention problems when allocating a cell pool block and to
    correctly maintain the anchor chains.
