USB Hard Drive Problems

What I have found is that if I boot with the USB HDD attached to the
system, the system will hang when starting to mount the file systems.

However, if I connect the drive after the system is booted, everything is
fine.  da0 appears, etc.

What should I be looking at to make the system boot with the external hard
drive attached?
