Confirmed on AWS AMI ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-20211129. We fixed it by reverting to kernel GNU/Linux 5.13.0-1025-aws x86_64, forcing GRUB to load it instead of a corrupted one.
P.S.: We faced loop rebooting and unkillable docker process. After the kernel downgrade, everything seems ok.
