--- Begin Message ---Package: watchdog Version: 5.12-1 Severity: important Tags: patch Dear Maintainer, wd_keepalive gets killed on shutdown from sendsigs. If the watchdog module runs with "nowayout", this leads to a hard reset after some time. This "some time" usually is very probably during the fs unmounting, which in turn probably leads to file system corruption. An exemplary case: Watchdog module: options bcm2708_wdog heartbeat=15 nowayout=1 rc6.d: lrwxrwxrwx 1 root root 18 Nov 24 2013 rc6.d/K01watchdog -> ../init.d/watchdog lrwxrwxrwx 1 root root 18 Nov 1 23:58 rc6.d/K07sendsigs -> ../init.d/sendsigs lrwxrwxrwx 1 root root 18 Nov 1 23:58 rc6.d/K11umountfs -> ../init.d/umountfs On K01, wd_keepalive is started, on K07 it gets killed by killall5 and on K11 the PC shuts down due to the hardware watchdog. It seems, the sendsigs init script (from package initscripts) has a mechanism to circumvent this, so it is easy to patch by adding a pid file to /run/sendsigs.omit.d like: ... on watchod start rm -f /run/sendsigs.omit.d/$KEEPALIVE_NAME.pid ... on watchod stop ln -s /var/run/$KEEPALIVE_NAME.pid /run/sendsigs.omit.d/$KEEPALIVE_NAME.pid Some own testing showed that this works flawlessly. Since sendsigs is from initscripts and watchdog depends on this implicitly, the directory can be assumed to exist.
