Support Note for Red Hat Enterprise Linux AS v.2.1 for the Itanium® Processor on HP Integrity Servers
Known Problems
Chapter 118
Known Problems
1. No support for uncertified .rpm packages.
If you add uncertified .rpms to the operating system, it will not be supported by Red Hat.
Red Hat supports only .rpms bundled in supported Linux distributions for Integrity
servers and official Red Hat Updates for those distributions. HP supports the Linux
software it distributes.
2. No support for systems with a recompiled kernel.
Although you may recompile your kernel to change configuration parameters, HP does not
support systems on which you have recompiled your kernel for any other reason, e.g. for
kernel source code changes.
Supported customizations:
a. Modifying configuration options found in
/usr/src/linux-version-versionnumber/configs to set values or make modules
static or dynamically loadable.
b. Changing boot-time parameters found in
/usr/share/doc/kernel-doc-2.4.18/kernel-parameters.txt (with the kernel-doc
.rpm) or in /usr/src/linux-2.4/Documentation/kernel-parameters.txt (with the
kernel-source /rpm.)
3. Installation failures:
a. If your media is an NFS directory containing ISO images and you are doing a custom
installation, do not select the “everything” package group. Doing so causes the
installation to crash.
b. If using CDs for a custom installation, do not select the “everything” package group.
Doing so causes the installation to crash in this case as well.
4. USB conflicts and system reboots.
Configurations that include a USB 1.1 mass storage device under the same OHCI root
hub as the USB keyboard can cause conflicts resulting in system reboot. You can use the
usbview tool to view the topology of the USB root hubs to avoid such configurations. If
improperly configured, refreshing the data in usbview while the USB mass storage device
is being accessed may cause your system to reboot.
To view the topology using usbview:
a. Launch usbview
