If I recall, the (easily undone) workaround was to remount from "data=journal" to "data=ordered" on a couple filesystems.

Bah... I went back to the old image that was crashing every boot before and I can't find any way to make it crash at all now... If I manage to reproduce it again later I'll send you another email.
