The switch is a Dell powerconnect 6248 with ports configured for aggragation. I first tried on a 9.1 prerelease, then on a 9.0 release to have everything clean. In both ssh, both as server and as client, become unresponsive and unkillable. The problem might also lie within ssh/d, but I somehow doubt it. I haven't tried other network services.
