Changes (by Quozl):

 * cc: godiard (added)


 * adding swap does not change symptom,
  * testing with [https://git.kernel.org/cgit/linux/kernel/git/stable
 3d861f66] (net: fix secpath kmemleak) does not change symptom,
  * adding a queue of preallocated socket buffers for use only when memory
 is scarce, and hiding the page allocation failure, (see
 [http://dev.laptop.org/~quozl/y/1Vgpjw.txt patch]), does prevent the
  * extending this to disable the interrupt (using device registers) when
 the queue is short, and enabling the interrupt when the queue is restored,
 does not work; there is a command timeout.
