This is exactly what happens when thermald messes with these Xeons, as long as your MSR 0x1b0 is also reading "7".So, could you check the output of "rdmsr 0x1b0" ?
MSR 0x1b0 is MSR_IA32_ENERGY_PERF_BIAS, which is included in the turbostat output (where in all cases it read `7')
The degradation still occurs when booted with newer firmware and msr.ko renamed (and hence not loaded).
