Linux Kernel Crash Dump facility

LKCD can be found at

http://lkcd.sourceforge.net/

“When kernel fault occurs, LKCD writes a copy of the current system state (memory primarily) into the dump device you specified in advance. The dump device must be a system swap area. A utility called LCRASH is run on the next reboot (before swapping is enabled) to generate a summary of the crash, and optionally to save a copy of the dump in a conventional file. LCRASH can be run interactively and provides a number of debugger-like commands for querying the state of the system.”
