USB failure on mpc8347 based board

[Grant Likely]

I'm seeing the following error on an MPC8347 based board.  The
physical board is wired up with the fsl-usb2-dr controller setup as a
USB device using port0 and fsl-usb2-mph as a USB host using port1.
The EHCI driver fails with the following error when initializing the
fsl-usb2-mph controller:

In particular I'm wondering if anyone knows the cause of "HC died; cleaning up".

The board has a hard wired USB hub connected to port1, and the host
controller seems to be dying while probing that device.

Cheers,
g.
