Hmm, probability-wise that is not very likely that at least 4 different 
machines (V240, V440, E450, V100) grow a hardware error at 4.3 timeframe 
and start rebooting spontaneously?

Maybe something with our memory detection / bootmeme / memory ranges has 
changed?

Il will try more to find a way to reproduce the problem. Maybe putting 
aside an old git tree state (how do I get one?), then at each boot copy 
it and pull it and then compile.
