Can you retry with the ia32e kernels (UP/SMP) ? Yes, I see that now: [root at polaris root]# rpm -q --qf "%{ARCH} %{VERSION}-%{RELEASE}\n" kernel ia32e 2.4.21-27.0.2.EL [root at polaris root]# rpm -q --qf "%{ARCH} %{VERSION}-%{RELEASE}\n" kernel-smp x86_64 2.4.21-27.0.4.EL However, I wonder why "yum install kernel-smp" chose the x86_64 kernel? Looking in the CentOS update repository, there is no ia32e directory. Inside the x86_64 directory, I see the following kernels: kernel-2.4.21-27.0.4.EL.ia32e.rpm kernel-2.4.21-27.0.4.EL.x86_64.rpm kernel-smp-2.4.21-27.0.4.EL.x86_64.rpm kernel-smp-unsupported-2.4.21-27.0.4.EL.x86_64.rpm kernel-unsupported-2.4.21-27.0.4.EL.ia32e.rpm kernel-unsupported-2.4.21-27.0.4.EL.x86_64.rpm Why is there no kernel-smp for ia32e? Based on the current kernel's behavior, I guess it's safe to assume the UP kernel will work for SMP, but why isn't it labeled accordingly? Is this just an oversight by the package maintainers? It would be great if someone could post a FAQ regarding these kernels for CentOS 3.4. Thanks, -- Jason Dixon DixonGroup Consulting http://www.dixongroup.net
