Quick question...are you using throttling/TCC? If so, either turn it off or limit how low it can run the CPU. When I was running throttling on systems with old Matrox and Radeon cards, they would freeze if the throttling went too low. As mav pointed out at http://wiki.freebsd.org/TuningPowerConsumption, TCC does little to conserve power and was not designed for that. TCC is Thermal Control Circuit and is designed to keep the CPU form over-temping. It works for this, but not power management. I'd love to see it off (for power management) by default. hint.p4tcc.0.disabled=1 hint.acpi_throttle.0.disabled=1 -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
