Still no fallback? Weird, would you apply the other patch that filters the __GFP_THISNODE flag and try again? Could you try to add some printk's to the page allocator to figure out what is going on there? Or is it clear that the node is overallocated? Could it be that the node online mask contains a node that has not been bootstrapped yet? Dont you have someone who can debug this? This is kind of an awkward back and forth with me guessing what the system does. Someone with knowledge about the way NUMA is implemented in the arch code? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
