I upgraded to 3.4.4 (identical config as the 3.4.0 build I've been running) and what can I say - the problem really seems to have disappeared. I performed about 3700 iterations of my previos tests over the night, and the data always turned out to be OK, not a single byte turned out kaput!
I wish I would have tested that earlier, and spared you the noise... well, maybe someone who runs into a similar problem in the future will have this discovery save her/him some time and headaches and make her/him just upgrade kernels :)
Thanks a lot for your polite and quick responses!
