Comment # 1 on bug 962235 from Takashi Iwai

This is a feature of systemd started in dracut initrd.  It takes all modules
listed in /usr/lib/modules-load.d and /etc/modules-load.d.

Yet, it's a bug of dracut that it fails to load the specified module.  It seems
that its module dependency resolver is incomplete.

I guess you can suppress it by adding a line in a dracut config, e.g.
/etc/dracut.conf.d/99-local.conf, something like:

omit_drivers+=" snd_aloop"

Though it's merely a workaround.  Dracut/systemd should have a better control
over this, above all.
