Requiring the machine again, and I got the following without nr_cpus option
[root@dell-per7425-03 ~]# cd /sys/devices/system/node/
[root@dell-per7425-03 node]# ls
has_cpu has_memory has_normal_memory node0 node1 node2 node3
node4 node5 node6 node7 online possible power uevent
[root@dell-per7425-03 node]# cat has_cpu
0-7
[root@dell-per7425-03 node]# cat has_memory
1,5
[root@dell-per7425-03 node]# cat online
0-7
[root@dell-per7425-03 node]# cat possible
0-7
And lscpu shows the following numa-cpu info:
NUMA node0 CPU(s): 0,8,16,24
NUMA node1 CPU(s): 2,10,18,26
NUMA node2 CPU(s): 4,12,20,28
NUMA node3 CPU(s): 6,14,22,30
NUMA node4 CPU(s): 1,9,17,25
NUMA node5 CPU(s): 3,11,19,27
NUMA node6 CPU(s): 5,13,21,29
NUMA node7 CPU(s): 7,15,23,31

For the full panic message (I masked some hostname info with xx),
please see the attachment.
In a short word, it seems a problem with nr_cpus, if without this
option, the kernel can bootup correctly.

What about the static variable
static inline struct zonelist *node_zonelist(int nid, gfp_t flags)
{
+ if (unlikely(!node_online(nid))) {
+ WARN_ONCE(1, "Try to alloc mem from not online node\n");
+ nid = find_best_node(nid);
+ }
return NODE_DATA(nid)->node_zonelists + gfp_zonelist(flags);
}

+int find_best_node(int node)
+{
+ static nodemask_t used_mask;
+ static DEFINE_SPINLOCK(lock);
+ static int best_neigh[MAX_NUMNODES] = {0};
+ int nid;
+
+ spin_lock(&lock);
+ if (likely( best_neigh[node] != 0)) {
+ nid = best_neigh[node];
+ goto unlock;
+ }
+ nodes_complement(used_mask, node_online_map);
+ nid = find_next_best_node(node, &used_mask);
+ best_neigh[node] = nid;
+
+unlock:

+ return nid;

I am puzzling about this. Does unlikely work for it?
