It's definitely looking like something SMP related: on my laptop, with everything other than the hardware being identical (Linux distro, kernel, numpy build, etc), I can't make it fail no matter how I muck with it. I always get '0 differences'. The desktop is a dual-core AMD Athlon as indicated before, the laptop is an oldie Pentium III. They both run the same SMP-aware Ubuntu i686 kernel, since Ubuntu now ships a unified kernel, though obviously on the laptop the SMP code isn't active.
