Maybe these things also need order-1 pages to work ;)

Any kmem_cache using order-1 or order-2 pages can not allocate new slabs

For example, TCP sockets can not be allocated anymore, and fork() might
not work anymore (kernel stacks need order-1 pages)

I dont remember your case, but do you use CONFIG_COMPACTION=y ?
