The issue is still present with 4.4.0-42. It's completely preventing me from booting into Ubuntu. The error message is as follows:
lvmetad is not active yet, using direct activation during sysinit rootfs: clean, 271911/1831424 files, 1561286/7323648 blocks Here, "rootfs" is my root filesystem (ext4), located on an LVM logical volume. I also tried the following kernels (from http://kernel.ubuntu.com/~kernel-ppa/mainline/) as well: - v4.4.14-xenial (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/) - v4.7.7 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.7/) - v4.8.1 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.1/) I installed these by booting a live cd and chrooting into the "rootfs" filesystem, and then updating grub. The problem is still present in all of these kernels (with the slight variation that the error message is only shown briefly, and replaced by a blank screen) ** Summary changed: - LVM-based server does not boot with kernel 4.4 (but works with 4.2) + LVM-based filesystem does not boot with kernel 4.4 (but works with 4.2) -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
