Fortunately, Linux doesn't have to prove itself anymore, these days.
Usually these things happen on really crappy hardware. I had a new HP
Proliant Blade server a few months ago, and it would randomly lock up

amount of pain on me. Finally, it was replaced with an identical
model, and all problems were instantly gone.
