Public bug reported:
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).
