2.2.16 Intel TCO Watchdog Timer Messages

Some server hardware does not support the Intel TCO watchdog driver. dmesg might display messages such as the following at boot time:

iTCO_vendor_support: vendor-support=0 
iTCO_wdt: Intel TCO WatchDog Timer Driver v1.05 
iTCO_wdt: failed to reset NO_REBOOT flag, reboot disabled by hardware 
iTCO_wdt: No card detected 
intel_rng: FWH not detected

To suppress this warning at boot time, disable the TCO watchdog timer driver by adding the following line to /etc/modprobe.d/blacklist-watchdog:

blacklist iTCO_wdt
