"Red Hat builds kernels that are optimized for different x86 versions. The options are athlon for AMD Athlon and AMD Duron systems, i686 for Intel Pentium II, Intel Pentium III, Intel Pentium 4 systems, and i586 for Intel Pentium, and AMD K6 systems. If the version of the x86 system is unknown, use the kernel built for the i386 version; it is built for all x86-based systems.
"The x86 version of the RPM package is included in the file name. For example, kernel-2.4.20-2.47.1.athlon.rpm is optimized for AMD Athlon and AMD Duron systems and kernel-2.4.20-2.47.1.i686.rpm is optimized for Intel Pentium II, Intel Pentium III, Intel Pentium 4 systems. After determining which packages are needed to upgrade the kernel, select the proper architecture for the kernel, kernel-smp, and kernel-bigmem packages. Use the i386 versions of the other packages."
This message started appearing in SuSE 10 on our machines that authenticate using LDAP. It is cured by taking compatibility mode out of /etc/nsswitch.conf. Compatibility mode is for NIS, therefore irrelevant to us, and is, it seems, poorly maintained. Here is a sample /etc/nsswitch.conf:
