Same users get similar problem: http://comments.gmane.org/gmane.linux.kernel.containers.lxc.general/3169 There is an update of lxc here: http://lxc.sourceforge.net/download/lxc/ No ebuild for this is portage. Thanks, LP Reproducible: Always
Something feels wrong on your system, as it works just fine here. Care to post your emerge -pv lxc and your .config?
no problem with CGROUP_DEVICES! :D sorry for troubble.
Added an extra check for CGROUP_DEVICE to be on the safe side.
