kernel/sched does not seem to contain anything too scary.

I know that -next20181005 works ok, and I know -next20181010 is
bad. Is there easy way to bisect using that information? I can do
bisect between -next and mainline, but that's a lot of patches and
thus not much fun :-(.

In the meantime, I reproduced the failure with T40p. Is there someone
with working x86-32 in -next?
