As reported by kumico on the forum :
there is a problem with the following part of /lib/udev/ ( udev 118-5 ):

depmods="$(/sbin/modprobe -i --show-depends $1)"

#sanitize our module names
depmods="$(echo $depmods | sed \
-e "s#^insmod /lib.*/\(.*\)\.ko.*#\1#g" \
-e 's|-|_|g')"

That sed line only works correctly if each module is on its own line.
However, echo $depmods in bash lose the newlines, so it doesn't work correctly.
It only matches the last module, and so all the module deps are ignored.

The easiest / quickest fix is probably the one proposed by kumico, adding quotes :
depmods="$(echo "$depmods" | sed \

Trying to fix the sed command to work with multiple modules on one line will probably be trickier and result in a more complicated command with no real benefit.
This task depends upon

Agreed, quoting depmods in that line is the quickest and easiest fix, as it preserves the newlines.
