Maybe, but I'm not sure (my PXA runs at 520MHz).

I don't think that's the problem.
With '-n 1000', everything is fine.
With '-n 10000', on a non-loaded machine, everything is still fine,
but on a loaded machine, I get the softlock.
With '-n 30000' even on an unloaded machine I get a softlock
most of the time.
I think I'll go and try to understand what switchbench actually
does and what happens on that softlock. Then I'll probably come
back with more questions.
