On PoE sites the MIPI-DSI panel can lose its init on a supply dip while the RK3566 keeps running; the UI may also hang or exit. Three layers: - hardware watchdog: systemd RuntimeWatchdogSec=20s (system.conf.d) - GUI: SdWatchdog pings systemd per swapped frame (WATCHDOG_USEC=30s, enabled by the binary so older versions run under the same unit) and writes run/qt.frame; buttontask.service gets Restart=always, NotifyAccess=main, TimeoutAbortSec=10s - bt-displaywatch (root, buttontask-displaywatch.service): kernel DRM/DSI timeouts, eth link down->up (PoE dip hint), stale UI frames, restart storms -> panel re-init (stop UI, fb0 blank 4->0, start UI), repeated -> reboot (max 3/day, never during OTA); incident log in /var/log/buttontask/ Manual recovery: hold one finger 10 s in the bottom-left corner (panels are single-touch). Delivered by OTA via bt-update sync_system; the web service runs `bt-update sync-system` at start for devices updated by an older bt-update. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
