This is a known (and frequently discussed) problem with the USB disk
support -- the driver needs contiguous memory and can't find it.  
Booting the system with the USB disk attached often helps; you can also 
do things like

	dd if=/dev/zero of=/dev/null bs=128m

and letting it run for a few seconds often works, too.
