Skyjumper from our Arduino forum posted this on the other forum, testing with this board that I had wirewrapped up here

And he ran the serial ports fast in his applicatio. We never did anything special for the serial ports with low pass filters.
I suspect poor wiring where the error is occurring.

Hm, I have been building a 1284P based product for a while and its serial intensive, no problems noticed here. I just wrote an app on my wire wrapped prototype with its 1284P in DIP. We'll see how long it runs.
Is there any info about what triggers this bug, or exactly what problems it causes?"
