<p></p> <p><b>New page</b></p><div><br /> Implementation Idea<br /> <br /> I think this can be achieved by modifying the driver that services the hardware watchdog. This driver is aware of the hardware timeout (say this is N) and the application can make it a rule to always service the hardware watchdog device (/dev/wtd) every N/2 seconds. The driver can now warn when it has not been serviced during the first N/2 and has N/2 left to dump this event somehow.<br /> <br /> --Leon Woestenberg</div>
