In case anyone is looking for a (sort of) workaround: a separate non-LVM boot partition (/boot as mountpoint) circumvents the problem.
I'm not sure how easy this is to set up on an existing system. I had the luxury of being able to do a clean install without much trouble. Of course, this "workaround" is a bit heavy-handed, and should not be necessary at all, as grub2 supports booting from LVM. But at least it allows having the rest of the root filesystem on LVM volume(s). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574333 Title: LVM-based filesystem does not boot with kernel 4.4 (but works with 4.2) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1574333/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
