Did you have
CONFIG_FAIR_USER_SCHED enabled in both cases?
Yes.

CONFIG_FAIR_GROUP_SCHED=y
CONFIG_FAIR_USER_SCHED=y


Interesting that you have CONFIG_FAIR_USER_SCHED. Do you have any other users on the system (are they running anything at the time of the benchmark)? Could you turn off CONFIG_FAIR_USER_SCHED and turn on CONFIG_FAIR_GROUP_SCHED. I am going to run some tests with 2.6.25-rc2 and Volanomark and see how that goes.
