USB_DEBUG should help - you should also enable UHCI_DEBUG. In the meantime I'll work out what that "overflow!" message indicates. You've mentioned this panic occurs when you're using mplayer - does it fault immediately when you start mplayer, some time in the middle or when mplayer stops? Also attached is a workaround patch for ehci which stops NMIs from being raised on my system, it'd be great if you could test this too. -- Thanks, Jeremy
