The RPi can't actually power itself off, but it used to be the case that if you rebooted it after setting up a certain register configuration, the firmware would put the device into a low-power state. This did work when it was first upstreamed. However, it no longer works. I believe this was due to a change in the firmware, which is why I don't always trust the firmware. I should really check what the downstream kernel does for power off now; I assume it must have changed since the code was upstreamed. -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
