ow.
static void *____cache_alloc_node(struct kmem_cache *cachep, gfp_t flags,
int nodeid)
{
struct list_head *entry;
struct slab *slabp;
struct kmem_list3 *l3;
void *obj;
int x;
l3 = cachep->nodelists[nodeid];
BUG_ON(!l3);
Maybe something got mucked up in our initial preparation of the zonelists.
I assume this is a recent regression. Is there any chance you can bisect
it down to the offending commit?
Thanks.

04231b3002ac53f8a64a7bd142fde3fa4b6808c6 is first bad commit
commit 04231b3002ac53f8a64a7bd142fde3fa4b6808c6

Memoryless nodes: Slab support
Slab should not allocate control structures for nodes without memory. This
may seem to work right now but its unreliable since not all allocations can
fall back due to the use of GFP_THISNODE.
Switching a few for_each_online_node's to N_NORMAL_MEMORY will allow us to
only allocate for nodes that have regular memory.

An attempt to allocate from an offline node? What NUMA architecture did
this occur on?
