We are still handing off threads with non-initialised stacks. APW: schedule: ffffffff805f0cd8 bad rsp flags=00000000 Kernel panic - not syncing: BAD STACK POINTER Interestingly this has remained unchanged for dispite the major churn -mm takes so this could well be the underlying issue as we almost always blow up randomly when we do this, in a mess with no stack to work with. Last time I tried to split search -mm1 and she was being a hideous pig, I just couldn't get any bit of it to compile without the rest. Will try and track this down with the new -mm. -apw
