Looking at interfaces definition - it is still using acient interface names which are no longer in use. Has this installation been upgraded at all? The interface name today should be encf5f0 today.
Also: 4 ./sosreport-s8330025-20160224080320/etc/sysconfig/hardware/config-ccw-0.0.f5f0 0 ./sosreport-s8330025-20160224080320/etc/sysconfig/hardware/config-ccw-0.0.eb4a Are present, which means that this system is not upgraded to have latest sysconfig-hardware package. Your installation is really old, and thus is no longer supported, as common with development series only up to date systems are supported. Please upgrade your instance to latest packages, and try to reproduce the problem. With new udev rules managed by chzdev interface bring up should be more reliable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1552788 Title: network lost after large number of reboots To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1552788/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
