Issues and Known Problems
1. You must use Service Pack 3 CD #2 to obtain bug fixes for the following problems:
a. A heavily loaded system (running computation and I/O) occasionally hangs.
b. Programs that use pthread_spinlocks are unable to access critical sections in code
when the process tries to lock the spinlock. The program’s processes then consume
total CPU.
See “How to Use the SLES 8 CDs for Operating System Installation” on page 7 for more
information on these problems and how to use the operating system media to install the
fixes.
2. No support for uncertified .rpm packages
If you add uncertified .rpms to UnitedLinux partner distributions, they will not be
supported. Only .rpms bundled in supported Linux distributions for Itanium 2-based
servers and official patches for UnitedLinux partner distributions will be supported.
3. 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.)
4. System is unbootable after adding new disks.
When you add new disks, the system may fail with one of the following messages:
