I think this is the correct fix, yes.

We need to keep in mind though, that udev currently does not install any
stop (K) symlinks in runlevel 0 and 6, but we rely on the killing spree
in sendsigs to kill the udev process on shutdown.

Which means, we'd need to start installing those K symlinks in 0 6.
For that, edit /etc/init.d/udev, add
# Default-Stop: 0 6
to the LSB header, then run

# rm /etc/rcS.d/???udev
# update-rc.d udev defaults
