In the last few releases for the ipod video 60/80GB, I noticed a possible bug. If you plug the player into a charger only connection, the rockbox software will display the usb port connection and then restart into apple firmware, as if it were connected to a computer. Once the apple firmware boots up, it then will restart, since it is on a charger only and no actual data connection is present. Once rockbox is restarted, the same thing happens again. It basically gets stuck in a loop; constantly restarting.
It has never done this in earlier (a couple of months ago) releases.
