Thanks for providing the dump. Unfortunately the Spectre system has bad thermal table values (Since Windows 10 is using more advanced tables, manufacturer didn't notice bad values impact.). So there may be more systems like this. So I want to implement some workaroud. Can you give me dump of

Performance is poor. The CPU (an i7-8550U) is running at 400MHz, and never speeds up, even when running some of the Phoronix Test Suite benchmarks. I can use cpupower to switch to the "performance" cpufreq governor, but cannot change the frequency with either governor. Here is the output of some experiments I ran while Phoronix's c-ray test was running. ______________ gjditchf@copperplate:/var/log$ cat /proc/cpuinfo | grep MHz cpu MHz : 400.008 cpu MHz : 400.002 cpu MHz : 400.002 cpu MHz : 400.003 cpu MHz : 400.005 cpu MHz : 400.003 cpu MHz : 400.001 cpu MHz : 400.004 gjditchf@copperplate:/var/log$ cpupower frequency-info analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.00 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 1.60 GHz.
