If you could also boot and run your current kernel on a vanilla glibc-based ELDK setup (likely 3.1.1 with 2.4/ppc kernels), we could check whether busybox raises new issues or not. The latest setup works perfectly fine here on an Icecube for instance, "yes" and "netstat" tests included. > Many thanks in advance > Roderik > > MAN Roland Druckmaschinen AG > Vorsitzender des Aufsichtsrates: Hanno C.
