<snip interesting examples>
Sounds to me that this undervolting functionality should be part of the kernel and happen automatically. I have no clue, though, whether people who do it, just get lucky and undervolting doesn't cause any other hardware issues, or there's a real reason for this power madness and if not done, power-related failures happen only on some boxes so they decided to do them on all.
Or maybe BIOS is nuts, which is not a stretch.
Srinivas, what's the story here?
