Ok. That looks *very* much like the same old "x86-32: Fix boot with
CONFIG_X86_INVD_BUG" problem that was supposedly fixed by commit
b4ca46e4e82a, but maybe something else in your config means that
there's yet another case of the same bug that Arnaud Lacombe just
hadn't seen.

Andy: any ideas?

Andy, the problem looks like another oops in
alternative_instructions(). But this one happens with -rc6 too, so
there's something else wrong - commit b4ca46e4e82a is already there.

Werner, can you send Andy your full .config?
