• Kernel panics and crash data on Linux: the previous boot's journal, pstore and netconsole

  After a Linux kernel panic and reboot, journalctl -b -1 -k reads the previous boot's kernel messages if the journal persisted; pstore (for example ramoops, where configured) preserves a panic record across a reboot even when the journal did not; netconsole sends kernel messages to another machine over the network in real time. kdump captures a full memory dump and is covered elsewhere.
