Important Information

This section provides information about the issues you may encounter when

you are installing or using Red Hat Enterprise Linux 5 on your computer.

X Multimedia System (XMMS) Media Player May Not Play Certain .wav

or .ogg Files

The XMMS Media Player with ADI 1984 Codec does not play certain .wav

or .ogg files. This issue does not affect the CD audio playback and nor does it

occur with Helix Media Player.

Command line media players such as aplay and ogg123 can play all .wav

and .ogg files.

A fix for this issue is expected in a future Red Hat Enterprise Linux update.

IEEE1394 FireWire Support

Drivers for IEEE1394 FireWire storage devices are not compiled and

included with the Red Hat Enterprise Linux 5 kernels. To enable FireWire

support, download the latest IEEE1394 FireWire device driver RPM from

the Dell Support website at support.dell.com.

swiotlb Parameter Needs to be Set for nVidia Video Driver With EM64T

for Systems With Greater Than 4 GB RAM

When using Red Hat Enterprise Linux 5 x86_64 with the OpenGL nVidia

video driver on systems with more than 4 GB of RAM, a kernel panic may

occur while running 3-D applications. This is caused by memory allocation

problems when using a 32-bit address-only capable device with a 64-bit

operating system with greater than 4 GB of RAM. If you are using the Dell-

nVidia driver available on the Dell Support website at support.dell.com, this

problem is resolved by the RPM. If you are using the nVidia OpenGL driver

downloaded from www.nvidia.com, complete the following steps to avoid

this issue:

1

Open the

/boot/grub/grub.conf

file in an editor.

2

On a running system, add

swiotlb=65536

to the end of each line

that begins with

kernel

.

3

Save the file and reboot the system.

12 Important Information

The Intel RAID Feature is Not Supported on Dell Precision Systems

The integrated Serial ATA (SATA) controllers on Dell Precision™ 390 and

Dell Precision 490 workstations have built-in redundant array of independent

disks (RAID) features. The SATA controllers can be configured to RAID and

non-RAID modes. The Intel

®

RAID features of the SATA controllers are not

supported on Linux. Dell recommends disabling the RAID features when

using Linux on Dell Precision workstations; and using Linux operating system

software RAID instead.

Slow Boot and Warning Messages on SATA

If a SATA controller has a vacant SATA port, the SATA device may generate

the following warning message and delay the operating system boot sequence:

localhost kernel: scsi1 : ata_piix

localhost kernel: ata1: port is slow to respond,

please be patient

localhost kernel: ata1: port failed to respond

(30 secs)

This issue does not cause any problems after the operating system boots.

A fix for this issue is expected in a future Red Hat Enterprise Linux 5 update.

Driver Update Model Updates Kernel Entries on GRUB Boot

Selection Screen

When using Red Hat Enterprise Linux 5 Driver Update Model or DKMS to

update kernel modules, multiple GRUB entries appear at the GRUB Boot

selection screen on system boot. The Driver Update Model creates modified

initrd images when it updates a driver required for system boot. This behavior

is expected and the default boot kernel contains the most recent applied

driver changes. For more information, see the Red Hat Enterprise Linux 5

release notes on the Red Hat website at www.redhat.com.
