                   RACAL INTERLAN EISA NETWORK CARD CAUSES SYSTEM HANGS

    PROBLEM:        The Racal Interlan ES3210 causes system hangs with no error
                    messages (silent hang) when transferring large files across a
                    windows NT network.

    CAUSE:          Faulty driver for the ES3210 network card is unable to process
                    large data files.
