Then from the command line in single user mode, poke around with dev.cpu.0.freq=XXX. You could disable p4tcc and acpi_throttle to see if that helps (hint.p4tcc.0.disabled="1"). > performance_cx_lowest="C1" > economy_cx_lowest="C1" I see you've disabled the potential Cx interaction. I'll look into that issue soon now that I have a system that exhibits this bug. -- Nate
