Public bug reported: Hi,
I was using Ubuntu 18.10 thermald package, but I noted that, after few seconds at max CPU usage (max temp), thermald send the signal to RALP to reduce the voltage of the CPU. It set the freq to minimum (800MHz in my case). But when the CPU is idle and temp is lowered (35-40ºC) it did not send the signal to resume normal operation of the CPU. I compiled the latest version of thermald from git (https://github.com/intel/thermal_daemon) and now everything works fine. I started to thought that the problem was the hardware or BIOS problem, as I disabled the CPU scaling on the BIOS, but intel_pstate continued doing freq scaling (I think for Turbo mode). But the real problem was Thermald. The latest version from git works really fine and it automatically disables and enable the Intel Turbo state and balance the freqs and fan control fine. My hardware is a Lenovo Thinkpad P52 with i7-8850H. I tested it using Ubuntu kernel and Kernel 4.20 optimized for i7 processor but with Ubuntu default config (except processor family="Core2/newer Xeon", Preemption Model="Preemptible Kernel (Low- Latency Desktop)" and Timer frequency="1000HZ". (Only changed those settings from make oldconfig and make deb-pkg).
