Could you please open a new bug report using ubuntu-bug tool and include systemd journal which includes failed boots? Just in case if this is not the same issue. As so far we have only reproduced this on s390x architecture. Please enable persistent journal first by doing $ sudo mkdir -p /var/log/journal -- Regards, Dimitri. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1623383 Title: Some restarts fail due to missing base devices Status in systemd package in Ubuntu: Confirmed Bug description: Arch: s390x Release: Yakkety / 16.10 This happens on some (but not all) system starts with Yakkety. In Xenial (which is using the same 4.4 kernel version the Yakkety systems were using when the problem was first observed) this did not happen. The system (LPAR) this was seen first was an upgrade from Xenial but since then has been freshly installed with Yakkety. The same behaviour is seen on a zVM guest running Yakkety. The attached syslog shows a failed boot, followed by one that did work. Note the "Found device .*(sclp|encc00).*" messages in the good boot. Those are missing in the bad attempt and as a result networking and console fail to be usable. Also note, those boots were 4.8 kernels but we saw this with 4.4 kernels, too. This might be a systemd problem / race, I just filed it into udev for now as that better matches the not finding basic devices symptom.
