Same problem with plain ext4 root partition. I have two systems configured very similarly with 16.04, one has this problem and another has not. But their hardware is different, so I'd make an educated guess that this is a timing issue. Good thing is that it appears benign.
BTW, I get three errors: /scripts/init-premount/plymouth: line 38: /sbin/plymouthd: not found /scripts/init-premount/plymouth: line 38: /bin/plymouth: not found [fsck displays its output here] /scripts/init-bottom/plymouth: line 18: /bin/plymouth: not found -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1525699 Title: Error message "/sbin/plymouthd: not found" is shown on booting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1525699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
