For what it is worth, my first thought when I saw this is that you probably
have a shared library missing on your RAM disk.  As suggested by Wolfgang,
use NFS and see where your system stops requesting files and what file it
(probably) was unable to find.  You can use binutils & company to figure
out what symbols/libraries are needed by /bin/sh, but it is generally
easier to just run it using NFS and sniff the ether.

BDI-2000: better than chicken soup for whatever ails you ;-)
