Cubian X1 , A10 nano+headless (microSD), hang up at first install at "Setting sysfs variables..."

Device: Cubieboard A10 OS: Cubian X1 "Cubian-nano+headless-x1-a10.img" (downloaded today)

My Cubieboard run for months (>12) old Cubian image. Now it's time to install Cubian X1 :-) I 'dd' the img file over a 16GB microSD, inserting it into my Cubieboard and power on. Serial TTL connected to my Linux Ubuntu PC.

System boot first time, make some changes, expand fs then reboot again. System goes on but it hang (serial doesn't work anymore):

(...omissis...)
[....] Starting enhanced syslogd: rsyslogd ok 
[....] Starting deferred execution scheduler: atd ok
[....] Starting periodic command scheduler: cron ok
[....] Loading cpufreq kernel modules... ok
[....] Starting system message bus: dbus ok 
[....] Starting Avahi mDNS/DNS-SD Daemon: avahi-daemon ok 
[....] Starting OpenBSD Secure Shell server: sshd ok 
SSL tunnels disabled, see /etc/default/stunnel4
[....] Setting sysfs variables...  ==> HERE SYSTEM HANG UP

If ethernet cable is connected, DHCP is leased correctly but Cubieboard is unreachable by ssh or telnet. It's looks to be dead : it's hang up at "Setting sysfs variables..." If ethernet cable is disconnected nothing change: system hang-up always at "Setting sysfs variables..." (I've read this old issue https://github.com/cubieplayer/Cubian/issues/36 )

Any idea ?
