Installed armbian 5.25 jessie legacy from scratch. No changes to network configuration.

 

Cubietruck:

 

- eth0 (wired ethernet) - DHCP - works fine

- WLAN0 - driver is loaded during boot - but not used at all

 

Default /etc/networking/interfaces config:

allow-hotplug eth0
iface eth0 inet dhcp

auto lo
iface lo inet loopback

Reboot hangs forever during shutdown while executing the following stop (!!) skript:

[  *** ] A stop job is running for LSB: Raise network interfa...13s / no limit)

Tried both possible solutions to define a timeout of 15 secs from http://unix.stackexchange.com/questions/186162/how-to-change-timeout-in-systemctl

 

But this does not work - it keeps saying "no limit".

 

Question is - why does i raise network interfaces during sytem stop anyway?

 

TIA

Tobias

I think it's related to bug in wireless driver (ap6210) which sometimes causes crash on unload / shutdown. If you don't need wireless, disable this module and you should be fine.

Thanks - you are right. I saw the crash during unload of the wireless kernel module but wouldn't guess that it was related.

 

Commenting the line ap6210 in /etc/modules fixed it.

 

PS: And even better - disabling WLAN also fixed that 10-20 seconds delay during ssh login

for speedup ure ssh connect just add to /etc/ssh/sshd_config

UseDNS no

and change this option to

GSSAPIAuthentication no

after restart ssh service

systemctl restart ssh.service

Its old hax for speedup ssh
