Just chiming in to say that I am seeing the same exact thing and so far nothing I have done has changed that. Hopefully like the other person said that it is simply buggy firmware that will be fixed soon. If anything changes I will post it here as well.

Thanks...that worked.

I am unable to change into directories that contain underscores _
or use underscores at all. I am at the latest firmware 0.1.6 b137. Any thoughts?
