Besides, this was the first boot of the laptop after upgrading it to the latest 9.99.92 (it was on an earlier 9.9.92) and the system was weird - boot took much longer than usual, networking didn't work until I restarted it manually. This sort of behaviour happens with it when I reboot it. I wouldn't read too much into this, posted the trace in case it looks interesting.

Ok, I have reviewed the code and I think I know what’s wrong… I misunderstood the semantics of (*fo_restart)().  Easy fix.
