I think that this is unlikely.
There can definitely be other agents that could reload watchdog's timer, of
course. It is even possible to do that via SMBus interface (where ICH acts as
slave). But I don't think that micro-controllers typically do that.
It's possible to monitor TCO_RLD value and see if it gets reloaded to TCO_TMR
value even after watchdogd dies a violent death.
