Note the following events that may occur on your system during start-up.

On systems with large memory configurations, the video monitor can take
from several seconds to approximately two minutes to display an image
at startup.
•
If you are running the Red Hat Enterprise Linux WS, ES, or AS
(Version 4) (x86-64) operating system, the system may display the
following on-screen message several times during start-up:
clear kernel mapping: mapping is split: will leak
memory
This message is specific to the operating system and does not indicate
a problem with your system hardware.
Overcurrent Events on USB Ports
Some USB devices can cause an overcurrent event on your system’s USB
ports. When this occurs, the system disables one or more of the affected USB
ports, and communication with the attached USB devices is lost. An on-
screen system message may appear noting the event, but this is not always
the case, particularly with devices connected to the rear USB ports. If an
overcurrent event disables your system’s USB ports, re-enable the ports by
restarting your system.
If overcurrent events persist, you may need to remove or replace the USB
device(s) connected to your system.
