A manual addition on the kernel boot parameter line via /etc/default/grub doesn't help. It looks like the kernel can't access the file system. lsinitramfs /boot/initrd.img | grep btr shows btrfs module as part of the initrd. kernel 5.10.0-13.14 didn't have this problem. System boots from it without issues. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu57 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: erik 1566 F.... pulseaudio /dev/snd/controlC1: erik 1566 F.... pulseaudio CasperMD5CheckResult: unknown CurrentDesktop: KDE DistroRelease: Ubuntu 21.04 InstallationDate: Installed on 2020-03-24 (322 days ago) InstallationMedia: Kubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20200324) MachineType: Dell Inc.
