Hi Alexandre,
I think I hit this problem with Ubuntu too. 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!
