FWIW, I'm seeing a potentially-related BUG in the same function on a v4.8-rc7 kernel without CONFIG_NUMA enabled. I have a number of debug options set, including CONFIG_PAGE_POISONING and CONFIG_DEBUG_PAGEALLOC. I've included the full log for that below, including subsequent failures. I'm triggering this by running $(hackbench 100 process 1000). Thanks, Mark. [ 742.923329] ------------[ cut here ]------------ [ 742.927951] kernel BUG at mm/page_alloc.c:1844!

FWIW, I'm seeing a potentially-related BUG in the same function on a v4.8-rc7 kernel without CONFIG_NUMA enabled. I have a number of debug options set, including CONFIG_PAGE_POISONING and CONFIG_DEBUG_PAGEALLOC. I've included the full log for that below, including subsequent failures. I'm triggering this by running $(hackbench 100 process 1000). Thanks, Mark. [ 742.923329] ------------[ cut here ]------------ [ 742.927951] kernel BUG at mm/page_alloc.c:1844!
