When the watchdog is already running at probe time it is constantly pinged until userspace opens /dev/watchdog. With the patch I sent earlier today the functionallity is also given, that is the machine resets iff I stop pinging. And when I do a stopping-close the worker looks for this in hardware non-stoppable device. Very nice, and also \o/ for the diffstat, Uwe -- Pengutronix e.K. | Uwe Kleine-König | Industrial Linux Solutions | http://www.pengutronix.de/ | -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
