Package: lxc
Version: 1:2.0.5-1
Severity: normal

Since I upgraded to a 4.8.0 kernel, I get these messages in my logs:

  Nov  5 18:02:08 hostname PAM-CGFS[6968]: Corrupt /proc/self/cgroup
  Nov  5 18:05:01 hostname PAM-CGFS[8574]: Corrupt /proc/self/cgroup
  Nov  5 18:05:01 hostname PAM-CGFS[8574]: Failed to get list of controllers
  Nov  5 18:05:01 hostname PAM-CGFS[8574]: Corrupt /proc/self/cgroup
  Nov  5 18:10:01 hostname PAM-CGFS[8612]: Corrupt /proc/self/cgroup
  Nov  5 18:10:01 hostname PAM-CGFS[8612]: Failed to get list of controllers

It seems to come from here:
