The coprocessor's watchdog feeder, looked after from the host, 2026-10-27
768: the coprocessor feeds its own hardware
watchdog from busybox's watchdog -t 5 /dev/watchdog, which its init script S15watchdog starts - the
same on vendor versions 21, 22 and 23, read on all three boards. Stopping that one process while
everything else on the coprocessor ran made the first XGS 3300's host freeze in the coprocessor's reset
a minute later, every time, until the host's own watchdog restarted the appliance. Two runs on the first
XGS 3300 (vendor version 23): what its host did in the minute before it froze, and the same stop with
scripts/xgs/feeder.py running.
