Hi Mark,
I boot from a usb hard disk and I don't really have to
do anything special. Well, actually I load modules
from a genkernel initrd but that doesn't apply here
since you built in the drivers.
This is the same exact kernel that you were using from
the hard drive, right? What's your kernel command
line? I assume that the error occurs when the kernel
goes to mount the root filesystem. Exact details of
that error may be helpful.
