Solution
- For the stable distribution (woody) on the i386 architecture, these problems have been fixed in kernel-source-2.4.18 version 2.4.18-13, kernel-image-2.4.18-1-i386 version 2.4.18-11, and kernel-image-2.4.18-i386bf version 2.4.18-5woody4. For the stable distribution (woody) on the alpha architecture, these problems have been fixed in kernel-source-2.4.18 version 2.4.18-13 and kernel-image-2.4.18-1-alpha version 2.4.18-10. We recommend that you update your kernel packages. If you are using the kernel installed by the installation system when the 'bf24' option is selected (for a 2.4.x kernel), you should install the kernel-image-2.4.18-bf2.4 package. If you installed a different kernel-image package after installation, you should install the corresponding 2.4.18-1 kernel. You may use the table below as a guide. | If 'uname -r' shows: | Install this package: | 2.4.18-bf2.4 | kernel-image-2.4.18-bf2.4 | 2.4.18-386 | kernel-image-2.4.18-1-386 | 2.4.18-586tsc | kernel-image-2.4.18-1-586tsc | 2.4.18-686 | kernel-image-2.4.18-1-686 | 2.4.18-686-smp | kernel-image-2.4.18-1-686-smp | 2.4.18-k6 | kernel-image-2.4.18-1-k6 | 2.4.18-k7 | kernel-image-2.4.18-1-k7 NOTE: This kernel is binary compatible with the previous kernel security update, but not binary compatible with the corresponding kernel included in Debian 3.0r1. If you have not already applied the previous security update (kernel-image-2.4.18-bf2.4 version 2.4.18-5woody1 or any of the 2.4.18-1-* kernels), then any custom modules will need to be rebuilt in order to work with the new kernel. New PCMCIA modules are provided for all of the above kernels. NOTE: A system reboot will be required immediately after the upgrade in order to replace the running kernel. Remember to read carefully and follow the instructions given during the kernel upgrade process.
