I needed to change a bit my setup: no more /etc/hostname.loXX as it was
created automatically now: I saw several "ifconfig: SIOCSIFRDOMAIN: File exists"
on boot (after "starting network"), and interfaces got configured but without
rdomain setted.
With the patch, it works well for tcp ("route -T 20 exec redis-cli -h
192.168.20.2"
is ok, whereas it timeouted before), but the host paniced with ping
(no reply before).

The system is remote and has ddb.panic=0, savecore saw the panic, but I
dunno if it will be enough: the stack trace seems buggy.
