Symptom

An SMP kernel -- a kernel with multiprocessor support (SMP means Symmetric Multiprocessor) -- has been installed during installation although you are using a single processor motherboard. This is confirmed by the output of uname -a, which shows the kernel 2.4.18-64GB-SMP. You have a Pentium 4 processor.

Cause

New Pentium 4 processors are equipped with "Hyper-Threading Technology". This technology can be detected in Linux by examining the output of cat /proc/cpuinfo. A technical explanation of ths subject is available at http://developer.intel.com/technology/hyperthread. As it says, "two programs or threads can execute simultaneously. Thus one physical processor looks like two logical processors to the OS and applications."

Solution

If the computer BIOS supports SMP (or an analogous option is activated in BIOS), the machine can be used as an SMP system
in Linux. When the SMP kernel is installed, it will seem as if two processors are available and /proc/cpuinfo will show two CPUs. In this case, everything is (more than) fine. CPU power will be better exploited thanks to the installed SMP kernel.

If your BIOS does NOT support SMP (which can be noticed through a single CPU entry in /proc/cpuinfo in spite of an available ht processor flag), you can use the SuSE standard kernel for single-processor systems instead of the installed SMP kernel. Proceed as follows for the installation:

Start YaST2 and change to the dialog Software -> Install/Remove software. Now you can uninstall the package k_smp, group System/Kernel, and select the package k_dflt for installation. The boot configuration will be automatically updated and the new kernel will be used after the system is rebooted.


Let me know if it works
