keep getting "exec: Permission denied" at booting

[rolf liu <rolfliu@xxxxxxxxx>]

I am running 2.4.31 on ab1550. When the start-up comes at the network
config, ifup tries to bring up the ethernet interface. Then there
comes tons of "exec: Permission denied" message. the box just stop
there.

I am running through the NFS root filesystem got from redhat, possibly
7.1. pretty old. Is there a newer NFS available?

Any suggestion?

thanks
