since it's not really reproducible (i failed to get it since then), how
about you push your fix upstream (it's an obviously correct fix), we
consider this regression fixed and i'll re-notify you if there's still
any problem left. It's not like there's any escape from make randconfig
bootup test coverage in the long run ;-)
