The page list was NULL and some access ended up freaking the kernel
and oom kicked in for some reason i still don't understand. Bottom
line things were going south in a split second leaving me with no log
or access, i thought it was accounting not working as it was what i
tested at the time. I should have tested accouting without the
patchset
