    TITLE: Manhattan P/V SMC PCI Ethernet Card

    SUMMARY

       The SMC PCI Ethernet card may hang under heavy I/O in a
       Manhattan P and V system when sharing interrupts.

       This issue applies to the following systems: 501500, 501502, 501503,
       and 501830.

    ISSUE

       While running Netware 4.1 on the Manhattan P or V system, the SMC
       PCI NIC may hang under heavy I/O when the card is installed in the
       second PCI slot, which shares an interrupt with the on-board NCR
       controller.  A cold boot may be the only method to gain access to
       the server.

    BACKGROUND

       The use of earlier versions of NCR and SMC drivers cause the system
       to hang.

    ACTION

       Ensure that all the drivers are current.
