The firmware on your external controller does not properly support the echo buffer used to perform domain validation.

I'm guessing there was a timeout. Not an uncommon problem with at least early firmware revisions of these *marginal* external controllers. You might be able to prevent these from happening if you lower the queue depth - at least until you get new firmware. -- Justin
