Can you compile ehci with USB_DEBUG defined and send me dmesg output?
Or at least last string from ehci driver. And same from if_em with
DEBUG_x defined.

And when deadlock happend, can you enter to debugger prompt? If can,
please send me trace list.

And if it not be hard for you, I need a `devinfo -v` output too.

Thanks for bugtesting. :)
