Stop.

*** Error code 1

I assume some commiters fail to detect breakages as they don't
assert MODULES_WITH_WORLD="YES".  I saw similar twice in 2018-07
See disparity in supposedly current boxes, with:
	ls -l /boot/modules; ls -l /boot/kernel/kernel

Cheers,

 Brexit ref. stole votes from 700,000 Brits in EU; 1.9 M young, more remainers
 had no vote; 1.3 M old mostly leavers died.  Advert lies paid by noses in the
 trough; some foreign funders fined. New referendum now! http://stolenvotes.uk
