Hardware Watchdog

Before deployment, x86 motherboards should have their Hardware Watchdogs tested. Intel calls them "TCO watchdog" stands for "Total Cost of Ownership".

Step 1: modprobe

modprobe i2c-i801
modprobe i2c-smbus
modprobe iTCO-wdt

The commands are case sensitive (uppercase matters) and will not produce output.

Step 2: dmesg

You should see some lines with "iTCO" in the "dmesg" output.

iTCO_wdt: Intel TCO WatchDog Timer Driver v1.11
iTCO_wdt: Found a Intel PCH TCO device (Version=4, TCOBASE=0x0400)
iTCO_wdt: initialized. heartbeat=120 sec (nowayout=0)

You need ALL 3 lines to be there.

Step 3: Test

cat >> /dev/watchdog
press "Enter" key twice

Wait while watchdog counts down, do NOT interrupt by pressing Control-C etc.
When twice the heartbeat value (120 sec in example above) has been exceeded, system should hard reboot! This system's hardware watchdog IS working.

If system stuck (e.g. hung at POST) turn it off, disconnect power for a few minutes and switch on again. This system's hardware watchdog is NOT working.
