Hi, the BCM2708 SoC contain a hardware watchdog, using it, would be a good solution for the people which are running a remote rpi 24/7 to avoid these sudden system freezes. The watchdog (bcmwd0) is found when booting, but I'm not able to use it with the watchdogd (which is using /dev/fido to communicate with the watchdog). Seems that something is still missing. Any ideas? root@pizelot:~ # dmesg | grep Watchdog bcmwd0: <BCM2708/2835 Watchdog> mem 0x2010001c-0x20100027 on simplebus0 root@pizelot:~ # /etc/rc.d/watchdogd start Starting watchdogd. watchdogd: watchdog_patpat failed: Operation not supported watchdogd: patting the dog: Operation not supported /etc/rc.d/watchdogd: WARNING: failed to start watchdogd best regards, Andreas
