I want to enable kernel crash dumps for my Debian 5.0.7 machine. The kernel version is 2.2.26 amd64.

How can I configure this?

A short answer, but...

Go to your kernel source (E.g. cd /usr/src/linux/ ) and configure the options for the next kernel (make menuconfig). Go to "Processor type and features". Enable "kernel crash dumps". (CONFIG_CRASH_DUMP=y)

Build new kernel, install.

Then read these for more background information: Linux-Crash-HOWTO.pdf and lkcd utils

And to check if it's already enabled: grep CONFIG_CRASH /boot/config-$(uname -r) –  Matthew Flaschen Feb 13 at 20:21
