- Add netconsole receiver on zippy to capture kernel messages - Configure beefy as netconsole sender to zippy (192.168.1.2) - Enable kdump with 256M reserved memory for crash analysis - Add lockup detectors (softlockup_panic, hung_task_panic, nmi_watchdog) - Add consoleblank=300 for greeter display sleep - Persist crash dumps and add analysis tools (crash, makedumpfile) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
