Thanks, that already helps. Can you now please enable debugging of the 'resume' initramfs hook (which seems to produce those errors) with:
sudo sed -i '1 s/$/ -x/' /usr/share/initramfs-tools/scripts/local-premount/resume sudo update-initramfs -u then reboot with the previous "debug=y" again, and re-attach /var/log/boot.log? Please also give me the output of cat /etc/initramfs-tools/conf.d/resume Thanks! ** Changed in: systemd (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1398025 Title: Errors messages like "error: /dev/sdb: No medium found" on booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1398025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
