I get the oops by simply running the program, without libvirtd,
lxc-tools or ns_exec (it sets up a mount namespace itself). Are you
running with slub debugging (poisoning) enabled? The bug causes
access to freed memory, so otherwise often nothing will happen
(the memory won't have been overwritten yet).

OTOH, I haven't tried 2.6.31-rc3 either (but it doesn't look like fixed
there too).

Best regards,
