Hm, that's no good.  Sorry for the long silence.  I have no better
advice than

 - try as recent a kernel as possible

 - try a custom kernel with CONFIG_DEBUG_KMEMLEAK enabled to make
   the problem easier to track down.

Is this a regression (i.e., did previous kernel versions work okay)?

Thanks for a clear report,
Jonathan
