Hi,

This is not a regression. Ubuntu is configuring the kernel with
CONFIG_FAIR_USER_SCHED, which changes the behaviour. You can utilize
the feature more effectivly with uevent scripts (to which I have
linked in an earlier comment)

CONFIG_FAIR_CGROUP_SCHED will allow finer control of group scheduling,
with the option not to use by not making any groups and putting
everything in just one group.

Thanks,
Dhaval
