And what kernel revision. I seem to have found a 'sweet spot' with a 
rock solid kernel right now, but for about two weeks after upgrading my 
dual p3 to a dual opteron, it was crashing every second day due to some 
kernel issues. Was never able to debug it though, since I'm sitting in 
Oslo (Norway) and the box is in Hamburg (Germany), so all I could do was 
  upgrading kernel/world small steps at a time until it survived a night ;)

But right now, it's pretty darn smooth. And the fastest box I've ever 
laid my hands on, locally or remote.
