triggered

---
(gdb) l *0xffffffff8096452a
0xffffffff8096452a is in alloc_bootmem_core (mm/bootmem.c:442).
437 unsigned long fallback = 0;
438 unsigned long min, max, start, sidx, midx, step;
439
440 BUG_ON(!size);
441 BUG_ON(align & (align - 1));
442 BUG_ON(limit && goal + size > limit);
443
444 if (!bdata->node_bootmem_map)
445 return NULL;
446
(gdb)
