Serge,
Thanks a lot, this explains everything.
With "dpkg -l | grep cgroup" I found cgroup-lite,
which includes /bin/cgroups-mount and /bin/cgroups-umount
scripts.
After removing this package and rebooting, cat /proc/mounts | grep cgroup
show nothing.
I don't know for what is this package intend

Hello,
Thanks a lot for your answer.
I reproduced the problem:
this is what I run: (after boot, in Ubuntu 12.10)
mount -t tmpfscgroup_root/cgroup
mkdir /cgroup/test1
mount -t cgroup -o cpuset,devices mytest/cgroup/test1
And I get:
mount: mytest already mounted or /cgroup/test1 busy
