So, here is my little contribution to the bug hunting:

System A:
   kmem_cache_alloc called by non-running (1) task from c017265c!
   kmem_cache_alloc called by non-running (2) task from c017265c!
  kmem_cache_alloc called by non-running (1) task from c01724d8!
  kmem_cache_alloc called by non-running (2) task from c01724d8
resolves to:
  c0172644 T skb_clone
  c0172480 T alloc_skb

System B:
  kmem_cache_alloc called by non-running (1) task from c0170214!
  kmem_cache_alloc called by non-running (1) task from c0170090!
  kmem_cache_alloc called by non-running (4) task from c010fa2c!
resolves to:
  c0170290 T skb_copy
  c0170038 T alloc_skb
  c010f86c T send_sig_info

The last one (send_sig_info) showed up a lot during shutdown, the other
ones during normal (idle) operation.

I hope this helps a bit,

Juri
