You can find what kernel modules are loaded using lsmod
.
However some kernel modules are required at stage 1 boot. Basically preloaded in the initial ram disk before switching to the root filesystem. These kernel modules are mostly needed to deal with peripherals, storage devices, filesystems and network devices. You may need to be wary of these required modules:
sd_mod
- SCSI, SATA, and PATA (IDE) devices
