Struggling to get a kernel crash dump as described here: https://help.ubuntu.com/12.04/serverguide/kernel-crash-dump.html
Configuration done as described, but echo c > /proc/sysrq-trigger only causes a crash without any dump being captured: system hangs with blinking capslock. % dmesg |grep crash [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.8.0-32-generic root=/dev/mapper/ubuntu-root ro crashkernel=384M-2G:64M,2G-:128M [ 0.000000] Reserving 128MB of memory at 720MB for crashkernel (System RAM: 3989MB) [ 0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-3.8.0-32-generic root=/dev/mapper/ubuntu-root ro crashkernel=384M-2G:64M,2G-:128M I did '/etc/init.d/kdump start' and sysrq is working as expected. /var/crash is empty.
