Is the various memory snapshot tools provided by /proc fs and > /dev/*mem* not enough? (/proc/vmstat, /proc/kcore (piped to xxd)), > /proc/iomem, /dev/mem (piped to xxd) etc) Well, kdump takes a dump when the system oopsed. It does more or less the same like LKCD, but it boots a crashkernel through kexec instead of dumping from the old, broken kernel. That's more reliable. But it's not for live debugging (system tap or /proc/kcore only works when your system is still *running* and not oopsed).
