Thank you for taking the time to report this bug and helping to make
Ubuntu better. The relevant dpkg terminal log says:

For troubleshooting, can you provide the output of lsinitramfs for the
working and the failing initrd?

** Changed in: initramfs-tools (Ubuntu)

Title:
  modules for non-existent hardware are loaded for unknown reason
  (Ubunntu 20.04, kernel 5.4.0-80-generic)

Status in initramfs-tools package in Ubuntu:
  Incomplete
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My laptop is Asus X302LA. I removed its HDD and plugged it externally via USB-SATA convertor. 
  To restore the system's bootability, I had to switch from MODULES=dep to MODULES=most in /etc/initramfs-tools/initramfs.conf and regenerate initramfs images by command 
  update-initramfs -u -k all
  After a successful boot I checked lsmod output and was surprised by a number of loaded modules for seemingly absent hardware. Like, inv_mpu6050 and ak8975. 
  Do I have a way to check this hardware is actually present and is reporting any meaningful data ?
  If no, do Ubuntu maintainers of linux kernel and initramfs tools have a way to avoid loading these modules when their hardware is absent ?
