Good news is Linus' rc8 tag *has the same issue* so the reason why
wireless-testing has it is rc8 *does indeed have it*.

So Peter, if there is something extra or missing from
linux-2.6-allstable head it certainly fixed my issues, will have to
try a new respin of it to ensure it wasn't a fluke. Odd thing too
though is even my distribution kernel (karmic rc8 generic) works fine.

At least now I can safely bisect between rc7 and rc8, or pull the
kmemleaks branch and see if that fixed.
