A bit of color commentary here... Laurie and I and a few other folks have been trying to debug the hangs that some people are seeing on these machines. He and I have identical hardware and he sees regular hangs, and I rarely see any (I think in the span of 7 months I've seen maybe 2 or 3 total). I've been using this machine in anger as a daily driver and I can't make it break and other people can't even make it a day without a hang. We've tried to debug the issue and narrow down what device(s) might be causing the problem, or what workload, etc, but nothing is pointing in any specific direction. We've also seen reports of "long slow death" crashes where existing processes continue to work for some time but nothing new can be execed, and eventually even the existing processes freeze. To me that sounds like a lock issue but it never happens on my machine and only infreqently elsewhere, so I can't really debug it. We'd like to know if others have similar machines and if they are stable or not. -ml
