    Some slab change, perhaps? There's nothing special about the init_bio()
    slab call:

    bio_slab = kmem_cache_create("bio", sizeof(struct bio), 0,

    Hmm, this looks strange. That bug happens if:

    if ((!name) ||
    in_interrupt() ||
    (size < BYTES_PER_WORD) ||
    (size > (1<<MAX_OBJ_ORDER)*PAGE_SIZE) ||
    (dtor && !ctor)) {
    printk(KERN_ERR "%s: Early error in slab %s\n",
    __FUNCTION__, name);

    It must be in_interrupt() triggering, perhaps something change in the
    boot sequence?
