Does your config include the following? CONFIG_MAXSMP=y CONFIG_NODES_SHIFT=10 CONFIG_NR_CPUS=8192 If so, then it's the same problem: there are no spare bits left in page->flags. Disabling CONFIG_MAXSMP should fix it, unless you really want to use 8192 CPUs and 1024 NUMA nodes :) Please let me know. Thanks!
