Maybe you are having endianess issues.  Did you do this
(makefs/mdsetimage etc) using a big endian platform like ixp425 or did
you use the the LE x86?  I would NFS boot the ixdp425 and use it to
build your rootfs. I have also had to use the FFS_EI option to solve
some rootfs problems on my slug in the past.
