Ok, so I enabled DEBUG_STACKOVERFLOW in addition to CONFIG_DEBUG_SLAB
and CONFIG_DEBUG_PAGEALLOC, and got the below today...so maybe it
is a slab issue?
0xc0238cdd is in dst_alloc (net/core/dst.c:124).
119 if (ops->gc && atomic_read(&ops->entries) > ops->gc_thresh) {
120 if (ops->gc())
121 return NULL;
122 }
123 dst = kmem_cache_alloc(ops->kmem_cachep, SLAB_ATOMIC);
0xc013912b is at mm/slab.c:3077.
3072 size = kmem_cache_size(c);
3073 local_irq_restore(flags);
3074 }
3075
3076 return size;
3077 }
