ten watchdog se na starsim raspbianu vypinal pro me nepochopitelne po startu systemu, v dmesg bylo "watchdog stopped"

resenim bylo prejmenovat dva soubory /usr/sbin/wd_keepalive a /etc/init.d/wd_keepalive na treba wd_keepalive.neverrun

kdyz to budes mit doma a ne na strese, tak zkus treba tuto fork-bombu, to by to melo restartovat

jinak nastaveni je mozne v /etc/watchdog.conf

tady mi to hlida navic sshd, a timeout nesel vic nez 15 sekund, limit HW, interval teda musi byt nejvic 6, lip dej i min

a v /etc/modprobe.d/watchdog.conf options bcm2708_wdog nowayout=0 heartbeat=15

s nowayout=1 se to sice nevypinalo, ale zase pri normalnim vypnuti se vypne sluzba watchdog, ale HW watchdog nejde zrusit a jak ten shutdown trva vic nez 15 sekund, tak se to restartovavalo pred vypnutim
