Public bug reported: == Comment: #0 - Thorsten Diehl <thorsten.di...@de.ibm.com> - 2016-02-03 12:52:53 == I IPLed a system (version 20101020ubuntu416), started the installer, configured a first network device with static IPv4 and connected via ssh to the installer. I chose "expert mode" and selected "Configure the network device" instead of continuing at "Choose language". I selected my second OSA device and accepted this configuration. Consequently I chose "Configure a network using static addressing" instead of continuing at the proposed "Choose language". And immediatedly this session wasn't reachable any more. A parallel ping to this session did stall at the moment, when I pressed "Configure a network using static addressing". Obviously this action dropped the default gateway - here the result when entereing a shell to debug the situation: ~ #>ip a s ip a s 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enccw0.0.f5f0: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 02:a2:0f:00:00:99 brd ff:ff:ff:ff:ff:ff inet 9.152.162.103/22 brd 9.152.163.255 scope global enccw0.0.f5f0 valid_lft forever preferred_lft forever 3: enccw0.0.b1c6: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 02:00:00:5b:9f:69 brd ff:ff:ff:ff:ff:ff ~ #>ip r l ip r l ~ #> The network interfaces are both down, and thus all routes were lost!! When I bring up the first interface manually ip link set enccw0.0.f5f0 up and add the route and the default gw: ip route add 9.152.160.0/22 via 9.152.160.1 ip route add default via 9.152.160.1 I can continue with the IP configuration of the second network interface
