Title: Ubuntu boot failure after upgrade to kernel 5.4.0-52 Status in linux package in Ubuntu: Incomplete Bug description: I'm on Ubuntu 20.04 LTS. After upgrading from linux 5.4.0-51 to 5.4.0-52 today, the computer boots into initramfs (Busybox) every time I reboot. No disk errors found there. If I use the grub menu to switch back to 5.4.0-51, the system boots and runs normally. This is on a Lenovo P53s laptop running Ubuntu only (no dual boot).
