This is on an Intel system, not OMAP or anything like that. The result was as expected; there were a few "can't reset device" error messages but they stopped after a few hundred ms. If they persist for several minutes then something else is wrong. On the other hand, we could change the priority of those log messages. They don't have to be errors or warnings.
