>Description:
The EFI bootloader ( bootx64.efi ) loads the "msdos" module on its own, and since the "msdos" module already is built into the kernel, the kernel prints the warning: 

[     1.000000] WARNING: module error: module `msdos' pushed by boot loader already exists


I have thoroughly checked my boot.cfg and did not find any "load" command to load any modules, the EFI bootloader loads the module on its own.
>How-To-Repeat:
The problem exists only if "modules off" is not of one the commands
>Fix:
Set one of the commands to be executed to be "modules off"
