Symptoms:
        PHNE_8991:
        SR 5000716860:
        A select() call which waits for the file descriptor
        associated with a program ZLU to become readable is not
        awakened when a message arrives on the ZLU input queue.
        The select call returns after the timeout has expired
        with the read fd mask indicating the ZLU fd is readable.

Defect Description:
        PHNE_8991:
        SR 5000716860:
        The driver zcom0 was calling selwakeup() with the wrong
        argument type.  For hp-ux 10.10 the type was changed from
        (struct proc *) to (struct kthread *), but zcom0 was not
        updated.

        SR None:
        Some errors in setting the spl level for inbound events
        were corrected in the axin driver.

Installation Instructions:
        Please review all instructions and the Hewlett-Packard
        SupportLine User Guide or your Hewlett-Packard support terms
        and conditions for precautions, scope of license,
        restrictions, and, limitation of liability and warranties,
        before installing this patch.
        ------------------------------------------------------------
        1. Back up your system before installing a patch.

        2. Login as root.

        3. Copy the patch to the /tmp directory.

        4. Move to the /tmp directory and unshar the patch:

                cd /tmp
                sh PHNE_8991

        5a. For a standalone system, run swinstall to install the
            patch:

                swinstall -x autoreboot=true -x match_target=true \
                        -s /tmp/PHNE_8991.depot

        5b. For a homogeneous NFS Diskless cluster run swcluster on the
            server to install the patch on the server and the clients:

                swcluster -i -b

            This will invoke swcluster in the interactive mode and
            force all clients to be shut down.

            WARNING: All cluster clients must be shut down prior to the
                     patch installation.  Installing the patch while the
                     clients are booted is unsupported and can lead to
                     serious problems.

            The swcluster command will invoke an swinstall session in which
            you must specify:

                alternate root path  -  default is /export/shared_root/OS_700
                source depot path    -  /tmp/PHNE_8991.depot

            To complete the installation, select the patch by choosing
            "Actions -> Match What Target Has" and then "Actions -> Install"
            from the Menubar.

        5c. For a heterogeneous NFS Diskless cluster:

                - run swinstall on the server as in step 5a to install
                  the patch on the cluster server.

                - run swcluster on the server as in step 5b to install
                  the patch on the cluster clients.

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHNE_8991.  If you do not wish to retain a
        copy of the original software, you can create an empty file
        named /var/adm/sw/patch/PATCH_NOSAVE.

        Warning: If this file exists when a patch is installed, the
                 patch cannot be deinstalled.  Please be careful
                 when using this feature.

        It is recommended that you move the PHNE_8991.text file to
        /var/adm/sw/patch for future reference.

        To put this patch on a magnetic tape and install from the
        tape drive, use the command:

                dd if=/tmp/PHNE_8991.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
        SUBSYSTEM_SHUT
        Before installing this patch, use the following command
        to shutdown the ACC subsystem and kill the ACC daemons.

           /opt/acc/bin/zmasterd kill

        The above command kills any of the ACC daemons that are
        still running, including zmasterd, zx25d, watch, zmlog,
        zmon, and znode.

        The kernel will be regenerated and the system will reboot
        automatically during the patch installation.
