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
