There's your problem - "/dev/ttydiag" uses the RedBoot interfaces
which are polled, so while you're waiting for characters to arrive
on the CLI, the system never sees any network interrupts and thus
can't schedule the network threads, etc.

You'll need to use an interrupt-driven serial device instead.
