I still have issues with this. In addition to questionable usefulness outside the watchdog framework, I'm not even sure this is right for watchdog framework. Watchdog timeout is not a description of h/w, but user configuration. I think the existing mechanisms of module param or kernel cmdline is the right way to handle this. Rob
