I have never seen this particular behavior triggered by software. If, by any chance,
this is more likely a hardware issue. Maybe the power supply is unstable or the
CPU is overheating.

That seems to be very unlikely a software problem. But if it was, it would surely be
a kernel problem.

I have absolutely no clue how that would even happen. The kernel doesn't simply power
off the system.

The machine might not be as heavily used on OSX and Wheezy as it is on sid.

Try running the machine with different kernels because that's the only possible origin
of such an issue.
