Any suggestions on how I could figure out what was really going on and
what would be a better fix would be greatly appreciated.

As Michael explained, it's the ASF heartbeat sent by tg3_timer() that
must be delivered to the chip within certain timing constraints.

If you had any watchdog devices on this machine, they would likely
trigger too and reset your machine :)
