If cluster domain idle state is enabled on the RB1, the board becomes significantly less responsive. Under certain circumstances (if some of the devices are disabled in kernel config) the board can even lock up. It seems this is caused by the MPM not being pinged during CPU idle (in the same way the RPMh is pinged when cluster idle is entered). Disable cluster domain idle for the RB1 board until MPM driver is fixed to cooperate with the CPU idle states.
