I can attest to this. Despite my machine working overall quite well thanks largely I suppose to the mesanet cards and hardware I do suffer occasional real time errors on my machine. It is just an annoyance but If I knew this when I ordered my board I would have gotten something different. As it is I will eventually upgrade to another board most likely when there is a consensus of one that works well for most applications available that several people have tried. Hopefully the mounting of the board itself will be at least similar in configuration to my atom so I don't have to redo the entire cabinet it sits in.
