In case nobody shot this bug overnight... More info

The problem is in one of the sysfs-backing-store patches. I backed out the 6
sysfs-leaves-* patches and my system boots OK. (My kernel *does* still have
fix-sysfs-symlinks on). It won't be till late afternoon before I have time to
play binary-search on the 6 remaining..
