There is about a gigabyte of memory on node 0. > The expectation to have memory available on the node that you > bootstrap on is not unrealistic. What exactly does "available" mean in this context? The console log I posted earlier showed node 0 as having an active PFN range of 32768 - 278528 (245760 pages, or 960MB), and then showed a "freeing bootmem node 0" message, *before* we hit the BUG. If "available" doesn't mean "there are active pages which have been given to the VM system via free_all_bootmem_node()", what does it mean?
