SLES9 SP4 hangs during install or startup on systems with quad-core AMD Opteron processors and over 4 GB of RAM

This document (3191716) is provided subject to the disclaimer at the end of this document.

Environment

Novell SUSE Linux Enterprise Server 9 Service Pack 4 (x86_64 architecture)

Situation

SLES9-SP4 (kernel-2.6.5-7.308) installs correctly on a system with a Quad-core AMD Opteron processor with over 4 GB of RAM. However, on the the initial boot after installation, the system hard hangs.

Resolution

This problem can be resolved through the following two steps:

1. Temporary limit the memory to less than 4 GB.

The problem can be worked around by limiting the memory to less than 4 GB. This can be done by physically removing RAM to reduce it to less than 4 GB. Or a boot parameter can be used to limit the memory that is used by SLES. The boot parameter is “mem=xxxx” where xxxx= a number less than 4000.


2. Install the latest kernel update to version 2.6.5-7.311 or newer.

After using the above method to limit the memory while the system is installed, the kernel can be updated to provide the fixes so that the full amount of memory can be used.
