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? - Ted
