Hi, Is the system fully updated since installing, or only selectively? I ask this, because i would expect the interface name to have been renamed and migrated to encf5f0 -> shorter prefix, and leading zeros stripped as of systemd 228-4ubuntu2. Installation was done with systemd just before that one. Just a curious note, not assuming it will actually fix this.
The fact that link state is down, and there is no ipv6 address configured is disturbing. Three units did fail: UNIT LOAD ACTIVE SUB DESCRIPTION * console-setup.service loaded failed failed Set console keymap * multipath-tools-boot.service loaded failed failed LSB: early multipath boot script * networking.service loaded failed failed Raise network interfaces Fist one is mostly harmless, and should be fixed in latest console-setup. Last one is disturbing. And second one: Is multipath expected to be setup on the system? There are errors from parsing the config files: "Feb 24 08:03:28 | error parsing config file" Regards, Dimitri. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1552788 Title: network lost after large number of reboots Status in linux package in Ubuntu: New Bug description: ---Problem Description--- network lost after large number of reboots (>500) Contact Information = pschm...@de.ibm.com ---uname output--- Linux s8330025 4.4.0-2-generic #16-Ubuntu SMP Thu Jan 28 15:44:18 UTC 2016 s390x s390x s390x GNU/Linux Machine Type = s390 z/VM Guest ---Steps to Reproduce--- reboot z/VM guest several times >500. After a large number of reboots the network interfaces doesn't come up any more. The z/VM guest boots fine, unless the missing network. Impossible to bring up network again manually. == Further debug shows that it is the "ip link set enccw0.0.f5f0 up" that is failing with "RTNETLINK answers: Operation not permitted". Looking for further debug assistance in determining why the CAP_NET_ADMIN check for the root user running ip might be failing.
