cgroup/loop Bad page state oops in Linux v4.2-rc3-136-g45b4b782e848

Hi All, We've gotten a report[1] that any of the upcoming Fedora 23 install images are all failing on 32-bit VMs/machines. Looking at the first instance of the oops, it seems to be a bad page state where a page is still charged to a group and it is trying to be freed. The oops output is below.
