modules.dep is used to work out the module dependencies, so we know
which minimal set of modules should be copied into the initrd:


If you copy too many modules into the initrd, then it will be huge and
boot times will be very slow, so knowing the exact set of modules
which are required is important.

Of course if modules.dep is broken then that won't work.

Do you understand who broke the file and/or why it was broken?
