Okay that makes sense. You have no node 0 with normal memory but the node
assigned to the executing processor is zero (correct?). Thus it needs to
fallback to node 1 and that is not possible during bootstrap. You need to
run kmem_cache_init() on a cpu on a processor with memory.
Or we need to revert the patch which would allocate control
structures again for all online nodes regardless if they have memory or
not.
Does reverting 04231b3002ac53f8a64a7bd142fde3fa4b6808c6 change the
situation? (However, we tried this on the other thread without success).
