wspoon: Increase watchdog timeout Increasing the watchdog timeout to 10sec to allow dynamic fan speed changes to continue until a BMC performance issue is resolved. The watchdog wasn't being pinged within the original 3 seconds. This would cause the fans to run at 100% PWM and eventually be marked nonfunction resulting in a system being shutdown. Temporarily, marking a fan nonfunctional when it's tach feedback speed is above the target speed for witherspoon has been removed. This would keep the system from being shutdown, however the fans are no longer under dynamic speed control after the watchdog trips. Increasing the watchdog timeout to 10sec prolongs dynamic fan speed control staying active. If the watchdog trips, issuing a reboot will allow dynamic fan speed control again.
