SCOPE

This issue applies to HP xw6200 Workstation systems when ALL of the following conditions are true.
Red Hat Enterprise Linux 3 Update 3 or Update 4 WS AMD64/EM64T
4–4.5GB of memory
SATA hard drive
FX1400 or FX540 graphics card
kernel boot option swiotlb=16384 is used
This affects HP xw8200 Workstation systems that meet all of the following conditions:
Red Hat Enterprise Linux 3 Update 3 or Update 4 WS AMD64/EM64T
4–4.5GB of memory
SATA hard drive
FX1400 graphics card
kernel boot option swiotlb=16384 is used

RESOLUTION

NOTE: This issue has been resolved in RHEL3U5. If you are using RHEL3U3 or RHEL3U4, then the
following resolution still applies.
HP recommends increasing or reducing your memory so that you are above or below the 4-4.5GB
boundary. This can be accomplished in a number of ways.
Modify your /etc/grub.conf and replace "swiotlb=16384" with "mem=4000m." This will
force your kernel to behave as if it has only ~3.3G of memory.
If possible, remove memory to get to 3GB or lower. (The memory sticks need to be removed
in pairs.)
If possible, add memory to get to 5GB or higher. (The memory sticks need to be added in
pairs.)
AMD64/EM64T Preinstalled HP xw6200 Workstation and HP xw8200
Workstation Systems Need to Have Accelerated Graphics Configured

DESCRIPTION

On HP xw6200 Workstation and HP xw8200 Workstation systems that have been pre-installed in the
factory with Red Hat Enterprise Linux 3 Update 4 WS AMD64/EM64T, the accelerated graphics
driver fails to configure during the factory preload process. You can determine if your system needs to
have the accelerated graphics driver configured by first determining if the unaccelerated driver is
currently being used:
# glxinfo | grep "direct rendering"
If this returns direct rendering: No, you are running with an unaccelerated graphics driver and
you will want to configure the accelerated driver.
If this returns direct rendering: Yes, you are running with an accelerated graphics driver and
no further actions are needed.
SCOPE
This affects all HP xw6200 Workstation and HP xw8200 Workstation systems that have been
preinstalled in the factory with Red Hat Enterprise Linux 3 Update 4 WS AMD64/EM64T.
