Have you applied updates since then? (Maybe they fixed their init script
since 2 years ago?)

$ diff -u yury.conf /boot/config-4.4.0-78-generic | grep '^[-+]' | wc -l
10384

So that's not Ubuntu's current 14.04 kernel config.

$ diff -u yury.conf /boot/config-4.2.0-36-generic | grep '^[-+]' | wc -l
10212

And it's not the oldest Ubuntu 14.04 config I have lying around (from a
year ago).

$ cd linux && make defconfig
$ diff -u ~/yury.conf .config | grep '^[-+]' | wc -l
4369

It's much closer to the current defconfig, but still significantly
different.

So you're using a custom config, and can't switch off a symbol.
