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-
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 ?
