All,

My ARM board boots from a USB mass storage device and
for the second time the the root mount fails. First is
was because the root mount wouldn't wait for the USB
stack to complete the discovery process. Now CAM seems
to have entered the picture:

There are no GEOMs at this point.

Anyone else seeing this?
