Symptoms:
        PHKL_5272:
        With multiple, active graphics processes on an MP system
        (without this patch), one or more of the processes may
        "hang".  Moving the mouse or killing off an "offending"
        process *may* allow others to continue.

Defect Description:
        PHKL_5272:
        In general, a graphics process *may* "hang" (but only on
        MP systems) when there is high framebuffer resource
        loading; namely on SkyHawks.  This condition has only
        been observed on an MP SkyHawk with 2 or more rendered,
        double-buffered, 3D animations; the rotating "Liberty"
        statues.
        Also included in this patch is a performance tweak for MP
        graphics and a fix for a crash during reboot (which was
        only observed once).

                cd /tmp
                sh PHKL_5272

        5. Run swinstall to install the patch:

                swinstall -x autoreboot=true -x match_target=true
                        -s /tmp/PHKL_5272.depot

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHKL_5272.  If you do not wish to retain a

        It is recommended that you move the PHKL_5272.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:

                swpackage -s /tmp/PHKL_5272.depot -x
                        target_type=tape -d /dev/rmt/0m PHKL_5272
