Thanks for the pointer to the fix!  Does that mean that the workaround
is to increase the kmemleak pool size?  I had been using the default
(16000) and it seems surprising that that it wasn't enough to even get
the kernel through a standard boot sequence.  Should we perhaps
increase the default mempool size?
