Warning.svg Warning: This kernel branch is currently frozen.

Essentially that means it is neither maintained nor supported, could contain security vulnerabilities and other bugs, and generally should not be used.

Please check the list of supported kernel branches at Download/kernel page.

Below you can find the change log and downloads for the latest version of 2.6.18 kernel.

You need only one kernel RPM so please choose the appropriate one depending on your hardware:

  • If your x86 (i686, IA32) machine has more than 4 GB of RAM, choose kernel-enterprise RPM.
  • If your x86 (i686, IA32) or x86_64 (AMD64, EM64T) machine has more than one CPU (or a CPU with hyperthreading), choose kernel-smp RPM.
  • Otherwise, use the plain kernel RPM (i.e. kernel).

For more info, see Kernel flavors.
