HP maintains that more of our customers, especially new customers,
will be adversely affected by NOT implementing this patch for the
following reasons.

1. HP issued a Customer Advisory for existing customers to use "pci=bfsort"
    in the boot command for these systems. Customers using pci=bfsort in
    their boot scripts will be unaffected by this patch.

2. Customers using only the two embedded NI devices will be unaffected.

3. Because of the use of labels for disk devices, they are unaffected.

4. New customers who must add pci=bfsort to their boot scripts have
    expressed dissatisfaction.

The only time this patch would induce any confusion for an existing customer
is upon the convergence of the following situations.

1. The user has not followed the instructions in the release notes
    for the DL360 and DL380,

    AND

2. The user has added NI cards to the option slots,

    AND

3. The user upgrades his kernel.
