Hi,
Sounds like a bug in the intersection of lxcfs and the kernel. So you
could open an issue at github.com/lxc/lxcfs and append the config file
and other info there. Then (bc not many ppl look there I think) you
can link to that issue in a reply in this thread (where a lot more ppl
look).
Thanks for bisecting!
